Calcutta Mint, Introduction of Machinery, 1790 to c1802

 

Summary

 

In 1789, a major report about the coinage of the Bengal Presidency concluded that the problems of batta as well as counterfeiting, filing, drilling etc, could be overcome by the introduction of coin production following the “European” method. John Prinsep, of course, had already done this but most of his machinery and skilled employees had been rejected by the Calcutta authorities and little capability was available to achieve the objective. Fortunately, the Calcutta mint master had employed Prinsep’s foreman and his assistant, the latter of whom was to make a significant contribution to the construction and operation of the new mint. Nevertheless, although milled gold coins were produced reasonably quickly, milled silver coins proved more difficult and were not produced in Calcutta until 1793. Even then, the production of silver blanks continued to be undertaken manually and it was not until 1802 that this part of the process was executed with machinery. Machine-made copper coins were first produced in 1795, although these first heavy coins proved too expensive, and in 1796 lighter copper coins were produced.

 

Detailed Discussion

 

Introducing the Machinery

The designs of the gold and silver coins produced in the Calcutta mint by 1790, were based on the coins produced in the Murshīdābād mint before the British had acquired control. The major difference was that the RY was fixed at 19 although the Hijri year continued to change annually. This annual change continued until 1202 on the gold and 1205 on the silver coins.

On 28th October 1789, a Mr Shore sent a long paper to the Calcutta Board in which he stated that a new coinage in the fashion of the European coinages, should be produced for Bengal. The Board considered the paper in their meeting in January 1790 [1]:

The Board agreed in opinion with Mr Shore as to the principle on which he proposes the recoinage of the rupees should take place, but previous to adopting them finally, think it necessary to ascertain whether the machines and implements for coining and milling money in the European manner are ready or can be procured or made in this country, and whether there are any persons who are acquainted with the manner of fixing them up and making use of them. The Mint Master and Lt Golding being in attendance are called before the Board…

 

The coinage was to be undertaken in all four mints in Bengal: Calcutta, Murshīdābād, Patna and Dacca and the mint master, Herbert Harris, provided a list of equipment that he considered necessary for undertaking the new coinage in the new way:

 

1 flattening mill

2 cutting machines

1 stamping press

2 milling machines for graining the edges of the rupees

12 brass ingots

Implements to be made to complete the machines for four mints

3 small cutting machines

2 stamping presses

7 milling machines for graining

To be purchased

2 flattening mills

Implements ready in the mint

2 flattening mills complete

1 small cutting machine

4 large cutting machines

2 stamping presses complete

Lieut Golding being asked whether with the assistance of the artificers in the arsenal, he could make all the above machines and implements for coining money in the European method, he replies that he is of opinion that he could make them without difficulty and that he entertains no doubt but that he could put them up.

Being asked in what time that machines for one mint could be completely put together so as to commence the coinage of money, he replies that it could be done in considerably less time than three months, and refers to a drawing of the machines delivered in by the Mint Master and executed by Mr Aspinshaw, the foreman of the mint, from which it appears that in three months one machine complete might be put together and rooms built for the reception of it.

The Mint Master being asked whether there are any persons in this country who are acquainted with the mode of coining money in the European manner, he replies that there are two under his department, Mr Aspinshaw, the foreman of the mint, and his assistant, Benjamin Hughes; that the former is at present dangerously ill, but that the latter is now in attendance.

Benjamin Hughes being called before the Board and asked if he was ever employed in any of the mints in Europe, replies that he never was, but that he is acquainted with the method of coining money, as practiced in Europe, having been employed by Mr Binseh (Prinsep?) at Pultah in the late copper coinage, which was performed with machines and according to the European method.

Being asked whether he is acquainted with the mode of putting together the European coining machines, he replies in the affirmative.

Being asked whether he understands the mode of milling or graining money and whether he could make the machines required for the purpose, he answers in the affirmative to both questions.

Being required to state whether he could cut the screws for the fly presses, he replies that he could.

Ordered that Lieut Golding be directed to proceed without delay to make such parts of the machines and such of the implements as are of the most difficult construction in order that there may remain no doubt of the practicability of making the machines and apparatus for completing the recoinage of the silver in the manner proposed.

 

Both Mr Aspinshaw and Mr Hughes had worked for Prinsep at Pultah and it is notable that Aspinshaw produced the drawings for the new machinery, although he died very soon afterwards, and Hughes was instrumental in building many of the machines and worked at the Dacca mint for several years (see later), before becoming foreman of the Calcutta mint. He died suddenly in 1804 [2].

London was informed of the new project in January 1790 [3]:

 

In the 37 paragraph of our letter, dated the 5th November, from the Revenue Department, we referred you to our proceeding of 25th October upon the defective state of the currency in this country. We have the honor to transmit, in the packet of the Melville Castle a memorandum of the articles wanted for the mints that we propose to establish, and beg leave to request that […] may be sent out by the earliest opportunity that offers. We are very solicitous that this application may be complied with as soon as possible.

 

In April 1790 London sent a letter supporting the proposed new coinage [4]:

 

We have traced upon your records the various methods that have been adopted for putting a stop to the exorbitant batta demanded by the shroffs and others on the exchange of silver for gold – your endeavours to remedy an abuse of such generally pernicious tendency are entitled to our warmest commendations. Your last dispatch of the 10th August 1789, has acquainted us that the evil tho’ greatly prevented is not yet completely suppressed; we therefore rely on the continuance of your endeavours for the final accomplishment of the intended reformation.

Lord Cornwallis in his letter of the 2nd of August has given it as his opinion that there appears to be no effectual remedy for the evil but a general new coinage of all the circulating silver of the country into rupees, or sub-divisions of rupees, of exactly the same weight, standard and denomination, and his Lordship has assured us that he shall spare no pain and neglect no precautions to accomplish, with safety, this salutary work. When we consider the proposition simply, and without having regard to local prejudices, our assent naturally, and, as it were, in an instant, follows the proposal. But we wished to learn the opinion that may have been formed of it by the natives and others upon the spot, and we are happy to find by the reports of the several commercial residents and agents in the provinces, entered on your commercial consultations of 22nd May last, and by the opinion of the Board of Trade on the subject, that by the establishing of only one single coin throughout the country, no inconvenience or loss of any consideration is likely to weigh against its utility. If the reports of our servants in the revenue branch (who we observe have been consulted) shall be equally favourable to the project, we trust his Lordship will be able to effect his purpose previous to his departure for Europe. We are aware that the measure will meet with great obstruction from the shroffs and others who have hitherto reaped considerable advantage in exchanging the various species of rupees that have hitherto passed current in the several districts. When once therefore it is resolved to carry the plan into execution the most vigorous measures must be adopted in order to render it effectual.

 

In the meantime work had been progressing on the machinery for the Calcutta mint. In May 1790 the mint master was able to report [5]:

 

I have to request you will lay before the Right Honble the Governor General in Council the accompanying schedules of the machinery and work done in the mint since the determination of his Lordship to strike the new coin after the mode practiced in England. In addition to this we have in many instances had the tools to make before we could begin the work.

The present pay of the die cutters in the mint is sicca rupees 185 per month but to perform the cutting as neat as they can do it, two other men whose wages amount to sicca rupees 120 per month are required for this mint alone, and two men for each of the other mints. This will increase the establishment to full 500 rupees per month. Mr Spalding who has been bred to the dye sinking business has offered to cut the dyes for all the mints and employ and pay the workmen for sicca rupees 500 per month, including his own wages, and I beg leave to recommend that his offer be accepted as it will save the Company the amount of his wages and we shall be always certain of having the dyes accurately cut, and the same for every mint.

Lieutenant Humphreys having informed me of an opportunity of supplying the mint with some very valuable tools, particularly in the dye sinking business, I have to request I may be permitted to purchase them for the use of the mints. The sum will not exceed sicca rupees 700.

The movement of the great wheel of the mill not being sufficiently quick to roll out the quantity of gold and silver we shall require, and finding if I began to coin immediately, I should in a few days be obliged to stop the business to add another pair of rollers, I have with the approbation of Lieutenant Golding, who constructed the mill, prepared the frame of another set of rollers in such a manner as to fit them on the spindle of the present, by which means, the wheel being very powerful, can turn both, and we shall have separate rollers for the gold and silver or apply both to the silver as occasion may require.

As soon as the new rollers are fixed, we shall begin to train the people in the several occupations of flattening, cutting, filing, adjusting, milling and striking in copper, till we get them expert enough at the business to commence the new coinage.

 

There then follows a list of the machinery that had been built (see Appendix at the end of this chapter).

Mr Spalding seems to have been a great find and managed to invent a new way of producing dies that required less labour and would be difficult for forgers to copy, although he felt that he should be well rewarded for his efforts [6]:

 

Since I wrote you last on the subject of dye sinking, I have made an improvement in the business which will enable me to do as much in an hour as I would before in three days. Some men would keep this improvement a secret but on the contrary I make it my boast, being convinced no advantage will be taken of my candour.

In consequence of this improvement, I beg leave to make some alteration in my proposal for salary. In my last letter I mentioned I would require natives to assist me. Now I want none, tho’ I must recommend the Company keeping and paying a native who I will instruct in the business, with the motive of providing against my indisposition.

In my last I mentioned I would engage to sink dyes for all the mints. At the time I wrote my letter, I was not aware of the probability of copper coin being wanted, and consequently an additional number of dyes required. But with or without the additional trouble of making dyes for the copper coinage, I consider I merit sicca rupees 500 per month as coiner and dye sinker and having found a method much more accurate than that of copying the dyes by hand, a method (mine is) which must preclude the possibility of the natives forging the dye.

And it ought to be considered the improvement I have made, instead of being any additional expense to the Company, is a saving, as I don’t ask so much as coiner and dye sinker as it would cost the Company for dye sinkers only, supposing the natives capable of sinking the dyes in the manner they are wanted, which however they are not.

 

From the extract above, it is apparent that a new copper coinage was under consideration in 1790, although nothing further was done for several years. It is also clear that Mr Spalding was responsible for centralising die production in Calcutta. This meant that dies were identical for all the mints and made it that much more difficult for the shroffs to charge batta on the coins from the different mints (despite the secret marks put on the dies, see chapter 5).

In June 1790 the Calcutta mint master, Herbert Harris, explained why the new coinage had been delayed and also informed the Board that he had identified another of Prinsep’s ex-workmen who would be very helpful to him [7]:

 

I have received your letter of yesterday desiring I will inform Government when the new coinage will commence and what is the cause of the delay.

When the first rollers were put up in order to try the mill, we found them very defective in many places and discovered that one pair was not sufficient to roll out the quantity of metal wanted, but as we every day expected new ones from Mr Golding, I had hopes the machine would soon be completed, as we had contrived the means of adding (with the concurrence of that gentleman) another pair of rollers of a different size to be turned by the spindle of the machine. To fit these we were obliged to make a new frame and cogs, also the necessary rack work for adjusting the rollers. As the nice parts of this could only be accomplished by Mr Hughes, the business proceeded slow.

When Mr Golding gave us notice of his having failed in the tempering of his rollers, it was necessary to consider how we could carry on the business with the present rollers, and it was judged expedient to construct a polishing machine, drawings of which we had from England, for to repair and keep the rollers in order. This machine is absolutely necessary were the rollers ever so good as they grow rough from the silver passing through them and require polishing every three or four months.

Mr Hughes is now employed making this machine and he declares it will now take him 20 days to finish it. He has also forged a pair of rollers, one of which is now turning in the lathe and has every appearance of being perfect, and I hope in a few days to be able to acquaint his Lordship that we have succeeded in tempering it.

A large stock of dyes was also necessary to be prepared before the coinage could be begun as the steel is very apt to fly from the pressure of the stroke.

Mr Spalding has pointed out to me a native who was bred up under Mr Aspenshaw in the Pulta mint and has obtained some knowledge of dye sinking, and is a very correct and ingenious workman. This man is at present in the employ of Mr Howatt, the coachmaker, as a painter, but as many of this trade are to be got in Calcutta, I see no hardship Mr Howatt giving him up, as the man wishes to work under Mr Spalding who assures me with the assistance of this man he shall be ready to commence the gold coinage in one month from this date.

 

The Gold Coins at Calcutta

On 21st July Herbert Harris was able to inform the Governor General that he would start minting the new gold coins in August 1790 [8]:

 

I am to request you will acquaint the Governor General in Council that I shall be ready to commence the coinage of gold after the Europe manner after the first of next month, and desire you will inform me whether the suspension laid on the coinage of gold bullion the 3rd September 1788 is to be taken off.

 

In response, the Board issued the following advertisement:

 

Ordered the following advertisement be published in the Gazette in the English and country language:

The Governor General in Council has directed notice to be given that his Lordship has been pleased to revoke the order that was passed on the 3rd December 1788  for suspending the coinage of gold mohurs at the mint, and that from and after the 1st of next month, August, gold bullion will be received there for that purpose and coined without charge to individuals.

It is further hereby noticed that from and after the 1st of next month, new milled gold money will be issued of the former weight and standard, and the gold now extant of the Calcutta coinage will be recoined on application at the mint, into gold mohurs of the new coinage, also into small money, that is halves and quarters, for the convenience of individuals, without any expense to them, and weight will be delivered for weight.

The new gold coin will be received by the Collectors of the revenue and other officers of Government in payment of the demands of the Company

 

On 31st July, Calcutta informed London that they were about to start minting the new gold coins [9]:

 

On the 21st July we were acquainted by the Mint Master that he should be ready to begin the coinage of gold after the Europe manner on the first of the following month, and we caused our advertisement to be published for the information of individuals declaring the conditions on which their bullion would be coined, and authorizing the new gold to be received by the Collectors of Revenue and other officers of Government in payment of the demands of the Company.

Lieut Isaac Humphrys and Lieutenant Golding, of the Engineer Corps have afforded very ready and useful assistance in superintending the construction of the machinery for the different mints, and inventing and executing some parts of it, particularly the milling instrument. The Governor General has been pleased to record his sentiments thereon, in our proceedings of the 21st July and, at his Lordship’s recommendation, we have acquiesced in granting such recompences which they had actually incurred, as we deemed them justly entitled to.

 

On the 28th August 1790, Harris was able to report that he had begun minting gold coins although some delay had been encountered when they changed from trial striking in copper, to gold [10]. This, of course, implies that copper trial coins might well exist:

 

I request you will inform his Lordship I have begun the coinage of gold mohurs after the Europe manner, that some delay has been occasioned by circumstances which we could not forsee. The proof impression of the dyes on copper were very neat and the round of the coin well preserved, but when we came to give the impression to the gold, which is very fine and soft, the boldness of the letters occasioned the coin to spread out of the circle on receiving the stroke from the stamping machine, and it became necessary to alter the dyes so as to make the relief on the coin less prominent.

We had no sooner got the dyes ready and were going to work than we found the house had sunk from the very heavy rains and were obliged to take down the laminating machine and lower it so as to make it work again. As none of the walls of the house are cracked I conclude the sink of the foundations has been pretty equal and I hope it has not endangered the building.

 

The gold coins produced at this time were probably those catalogued by Pridmore in his Bengal Catalogue (Pr 61) and herein numbered 4.1.

 

  4.1

The first milled gold coins

 

Having decided that the new coinage would be difficult, if not impossible, to counterfeit, it is interesting to note just how quickly that happened (August 1791) [11]:

 

…A case has lately occurred which has occasioned some embarrassment and may in future be attended with very great inconvenience. By the proceedings referred to in the margin, you will observe that an attempt has been made to imitate the gold mohurs of the new coinage, and considering the defective means which must have been employed on the occasion, with some success.

The Advocate General’s opinion has been desired, whether any statute is in force, applicable to this country, by which coiners or the utterers of false coin, may be brought to punishment.

 

In August 1792 the Mint Committee was able to report [12]:

 

The size, shape and impression of the gold mohurs appear perfect, and fully equal in every respect to the newest English guinea, or any of the gold coins in Europe. The die is precisely of the same size as the coin, on which the whole impression consequently appears; the letters are cut flat and therefore liable to as little injury as possible from wear, and from being milled and of a proper thickness, it must be difficult to drill the coin without defacing it so as to render the fraud easily discoverable.

The machines and implements for striking and milling the gold coin, if not exactly similar, appear to answer those purposes as well as the milling and stamping machines used in Europe. Owing to some defect in the laminating machine which prevents it being used for preparing the planchets, the blank is made first with a hammer, and afterwards struck in a mould with a fly-press flat at the extremity, which expands the blank to the exact size of the mould and renders the blank as perfect as if cut with the cutting engine out of a slip or plate prepared with a laminating machine.

 

 

 

Thus the production of milled gold coins proved relatively straight-forward, and from October 1792 the daily output of gold coins from the Calcutta mint is reported in the records. It is interesting to note that the production of halves and quarters had started by 1793. Pridmore had not been able to find any reference to these fractions before 1796 [13]. In fact, after the initial output of mohurs, it was found that the fractions were much more useful than the whole mohurs, and the mint concentrated on producing these small coins for quite some time, as can be seen from the graphs.

 

Production of gold coins at the Calcutta mint

 

The Silver Coinage at Calcutta

At the meeting held on 1st September 1790, it was agreed that the following notice should be issued [14]:

 

Notice is hereby given that the new milled silver coin will be issued from the Honourable Company’s mint from and after the 10th instant in payment of the produce of all silver bullion sent to be coined.

The shroffs, money-changers etc are positively forbidden to deface, cut or clip the edges of the new coin or to put any private mark thereon. They are also prohibited from exacting any batta on the old nineteen sun sicca under pain in either case of incurring such punishment as the Governor General in Council may think proper to inflict.

 

London was informed that silver coinage would be started, but using the “old mode of coinage” in November 1790 [15]:

 

… and the silver coinage has also been begun upon. We were under the necessity, however, of allowing the old mode of coinage to be continued for some time until there should be a certainty of carrying on the business of the coinage by the new mode to its full extent, so that no interruption or unnecessary delay might take place, to the injury of the merchants and shroffs, & that a free importation of bullion might not be prevented.

 

The notice announcing the new milled silver coinage was premature. By February of 1791 it had become clear that using the laminating machines that had been built to roll out the silver was more troublesome than had been anticipated. The mint master therefore decided that producing the blanks by hand would be a more effective way of doing things for the time being [16]:

 

I am to request you will acquaint the Honble the Governor General in Council that I have tried the new method proposed by Mr Spalding of preparing the blanks by striking them with a hammer to the proper size for milling, and tho’ this method required a great many people yet it is preferable in many respects to the laminating mill and approaches very near to the method practised by the natives.

 

The Calcutta mint was able to produce 2000 rupees worth of gold coin and 120,000 rupees worth of silver coin in a week [17], but probably not milled silver, and in May 1791 the mint master was able to answer the following questions [18]:

 

Question: Supposing the whole mint establishment solely employed in coining silver. What number of rupees could be coined daily?

Answer: The rupees at present are made in the old way, and are struck with the fly presses instead of the hammer, which alone is a great improvement; and in this manner I can coin twenty thousand rupees per day.

Q: Supposing the whole mint establishment solely employed in coining gold. What number of mohurs could be coined daily?

A: The gold being coined after the European manner it would take some time to perfect the people in filing and adjusting the planchets, and I think five thousand gold mohurs per day would be as much as I could perform. In cutting out the planchets, or milling the edges, there is no difficulty.

Q: Supposing the whole mint establishment employed in coining partly gold and partly silver, what number of mohurs and rupees could be coined daily?

A: I now coin about 18 or 19,000 rupees per day in silver, and 500 gold mohurs. The proportion of silver to gold coined is as 4 to 1

 

In August 1791, Bengal updated London on the progress that had been made so far [19]:

 

Our advices by the Princess Amelia informed you that the new silver, as well as the gold coinage, had been actually commenced. Everything relating to this subject, either as it respects the mint established at the Presidency or at the cities of Patna and Dacca, will be found in the proceedings referred to in the margin.

The buildings in the old fort, formerly appropriated to the use of the mint, having been pulled down, and the temporary accommodations afterwards provided for this purpose, being found exceedingly inconvenient, we complied with an application made to us by the Mint Master for the hire of a house and go-downs, which he represented as being well calculated for conducting the business of his office in all its branches, at a rent which we presume will be thought sufficiently moderate, being Sa.Rs. 400 per mensum.

By our orders of the 1st December 1790, and the 14th January 1791, individuals delivering bullion into the mint were allowed to take away immediately from the treasury the amount of its assay value; but, in consequence of a representation made to us by the Accountant General on the 21st of April, from which it appeared that the available balance at the treasury fell short of the demands upon it for the discharge of bills which would become due before the first of May ensuing, we were under the necessity of suspending the operation of the orders in question until the amount of bullion, deposited for coinage, should be diminished…

…It being important to ascertain with as much precision as possible, the quantity both of gold and silver coin which, in a given time, could be worked off at the mint, certain queries were proposed to that effect to the Mint Master, adverting to the period when the buildings lately engaged for the purpose, should be in a state of perfect preparation. These, with the Mint Master’s answers, will be found recorded in the proceedings of the dates annexed…

 

The silver coins produced at this time must have been the 19 sun sicca dumps dated AH 1205. Hijri year 1205 ended in August 1791, but these coins seem to have been produced for a lot longer, probably until 1793 in Calcutta and even 1794 at the subsidiary mint of Dacca (see chapter 5).

By May 1792, it had become obvious that the early optimism about the speed of implementing a machine-made silver coinage was ill-founded. The Calcutta mint was producing a silver coinage using fly-presses to stamp the blanks, but the blanks were produced by hand. The Governor General therefore decided to appoint a committee to look into the problems and provide a way forward. The committee was to comprise Mr Herbert Harris, Mr Barlow, Mr Caldicott and Lieut Golding and they were to investigate why it had taken so long to get the new coinage up and running, what was happening with batta and the need for a copper coinage, amongst other things [20].

In the same month, August 1792, the Mint Committee was able to report [21]:

 

…With respect to the silver coin, it appears to be very defective with regard to its size, thickness and impression. The blank is made with the hammer; the impression is struck with a fly-press but with a die of twice the circumference of the coin so that only a part of the impression appears upon it. The letters also, instead of being flat like those of the gold mohur, are prominent and pointed, and consequently liable to greater injury from common wear, as well as from filing. From being very thick and not milled it may be easily filed and drilled, and is liable to be defaced and debased in other ways, so that no person can receive it with safety without having it examined by a shroff.

We beg leave therefore to recommend that in future the rupees be coined and milled in the same manner as the gold mohur and that the Hijeree are to be omitted, as the insertion of it, by shewing the year in which the rupees are struck, defeats the object of Government in continuing the 19th sun or year of the King’s reign upon the coin.

We beg leave to submit specimens of rupees coined and milled in the manner proposed, and should they meet with the approbation of your Lordship in Council, we shall take the necessary steps for preparing the requisite number of fly-presses and other implements with the least possible delay, continuing in the meantime to coin the rupees in the former method, until a sufficient number of machines and implements are completed to enable the Mint Master at Calcutta and the Assay Masters of the the other mints to coin the new rupees with equal expedition.

 

The Board agreed with the proposals, notably that the hijra date should be omitted, and they approved the specimens submitted.

Further information on the production process, and particularly when the milled coinage of rupees began in the Calcutta mint, was given by the mint master, James Miller, in October 1793 [22]:

 

…But since the commencement of the milled silver coinage from and after the 31st August last [i.e. August 1793], the powers of the mint have been greatly abridged in regard to the quantity of the whole coin that can be produced in the same time, even with a considerable augmentation of dye-feeders, lever-men etc, because of the increased quantity of labour which is required in the new silver coinage beyond what was necessary in the old.

At present every blank receives three blows, one from a concave dye, another from a collar dye and a third from the letter dye, which compleats the coin, and between each of those blows the same blank must be annealed to soften the silver so as to prevent its cracking towards the edge, until which caution was observed, many blanks were obliged to be wholly reformed.

In the old way of coining silver, the duraps formed the blanks with a few careless blows of the hammer, for, as they were not to be milled, it was of little consequence whether they were perfectly round or not, and the diameter of the rupee was chiefly determined by the force of the blow with which the impression was made, and the ductility or hardness of the metal. But few blanks were spoiled in comparison with those of the present coinage…

 

From this information we can attempt to recreate the process that was used in making the coins at that time. Blanks would have been cut by hand and weighed and the weight adjusted. Then they were struck with a concave die, probably in a collar, presumably to get them to the correct diameter. Next they were struck with the “collar die” to “give a smooth surface to the rim” (see p. 369). Finally they were struck with the dies bearing the Persian inscription. Between each striking they had to be annealed. This whole process was laborious and time-consuming. After this the edge milling was added using a process that is not described but which, in Calcutta, was carried out by boys from the orphanage [23]:

 

The Mint Master at Calcutta having applied to us for an additional number of boys to be employed in milling the coin, we beg leave to request that your Lordship in Council will be pleased to authorize us to apply to the managers of the orphan society for four boys for the above purpose.

 

As well as agreeing that the Hijri date should be omitted and the silver coins struck in the same way as the gold, Bengal reported to London in December 1792 [24]:

 

Since the beginning of October the Mint and Assay Masters have delivered into the Board a daily return of work done at their respective offices, a measure of obvious utility…

…Towards the end of October, the operations of the mint had become so much more expeditious that we were able to revoke the permission granted on the 31st August, to individuals delivering bullion at the mint, to exchange mint certificates for 8 per cent promissory notes, instead of waiting to receive in coin the produce of their bullion. This indulgence ceased from the 17th November…

 

As stated above, the mint master had been asked to provide a daily report on the activities of the mint, and this report included the number of coins struck, by value. It is not possible to tell how many of each individual denomination were struck to start with, simply a rupee value for silver. It seems likely that only whole rupees were produced initially because, at a later date, the number of half and quarter rupees is stated (see graphs below).

Calcutta continued to produce the blanks by hand, although a trial of laminating and cutting machines was performed at the end of 1794 [25]:

 

From the late enquiries however, in which I have been engaged in regard to the flaws too often to be found in blanks which had been fashioned by the hammer, I became sensible of the necessity of endeavouring to bring into actual and constant practice the mode of forming them by means of the laminating and cutting machines. Those blanks which are formed by the hammer require and receive two separate blows in the presses between what is called the collar and concave dies, respectively, before they receive the last blow between the dies which give the impression of the coin. Each of these blows renders the metal more rigid and brittle, which causes the necessity of annealing all the blanks by making them hot to redness, both between the first and second blows, and between the second and third, which occasions not a little loss of time. Notwithstanding the above method of softening the metal, it sometimes happens that blanks which were formed even free from flaws when delivered from the hammer have exhibited cracks more or less considerable, after each blow, and after having sustained the two first, have under the last been rendered unfit to be issued from the mint as coin.

I therefore caused a trial to be made of the laminating and cutting machines, the blanks formed by which require no other blow in the presses than that which gives the impression. This trial was made upon about 1000 Sa Rs, the coin produced from which appeared to be most perfect in every respect, but of greater diameter in a small degree than that which had been before approved of. The cutting machines have been accordingly reduced, and I am now giving out considerable quantities of the Dutch silver to be formed into whole rupees in the above manner, to enable the Honble Board to judge of which, I have herewith the honor to enclose two rupees of the coinage by the hammer, one of the sort which I had found to be to large by the cutters and one of those produced since the cutters were contracted.

This mode of coinage may, I am sensible, occasion additional expense in some instances, whilst in others it will effect a considerable reduction, because it will render about two-thirds of the pressmen and dye feeders unnecessary. In the meantime I continue to occupy most of the duraps in the old way, and only employ a few of the sardars in adjusting the blanks, which are formed after the laminating method. The sardars however, I am sensible, would not be friendly to the establishment of this mode of forming the blanks unless they could obtain such wages for adjusting them as would compensate for the loss of the docauns, and the advantages they derive between the wages they pay to the people they employ, and the amount allowed for each set. But if this should be the case, other people for adjusting the blanks must be sort for and entertained.

The Honble Board, I cannot therefore doubt, will be satisfied that a change of this nature must be effected by degrees and in such manner as not to occasion any stop or impediment to the coinage…

 

 

An important point to note from the above extract is that the trial produced approximately 1000 pieces, which were of slightly greater diameter than the normally produced rupees. This observation is important for attributing the different coins to their time of production (see below).

In fact, Calcutta did not introduce the laminating and cutting machines until 1801, and this was not formally confirmed until 1802 (see Chapter 6), so it actually took more than ten years to fully mechanise the mint.

The graphs on this and the following page show that, like the gold coinage, the mint began by producing whole rupees and, once this had been perfected, the mint concentrated on producing the fractions. It is also interesting to note the reduction in coinage, mentioned by the Mint Committee, following the introduction of the milling process in 1793.

The output of silver coins from the Calcutta mint

 

Regulation for the New Coinage

In October 1792, following the review by the Mint Committee, the Governor General published an advertisement formally announcing the new silver coinage, and that, as from April 1794, the only coins acceptable as currency would be the 19 sun siccas [26]:

 

The following regulations for the conduct of the several mints having been adopted by the Governor General in Council are now made public, together with the subjoined table of rates of batta for general information

First: that after the 30th Chyte 1200, Bengal style, corresponding with the 10th April 1794, only the 19 sun sicca rupee be received at the public treasuries or issued therefrom on any amount whatsoever.

 

Second: that public notice be given that Government, with a view to enable individuals to get their old coin or bullion converted into sicca rupees without delay, have established mints at Patna, Moorshedabad and Dacca, in addition to the mint at Calcutta.

Third: that for all bullion or old coin of sicca standard delivered into the mint, an equal weight of sicca rupees be returned to the proprietor without any charge whatsoever.

Fourth: that all bullion or old coin under sicca standard delivered into the mints be refined to the sicca standard and that a number of sicca rupees equal to the weight of the bullion so refined be returned, after deducting twelve annas per cent for the charge of refining.

Fifth: that the rupees coined at Dacca, Patna and Moorshedabad be made precisely of the same shape, weight and standard, and that they bear the same impression as the 19 sun sicca rupee coined at Calcutta, in order that the rupees struck at the several mints may not be distinguishable from each other, and that they may be received and paid indiscriminately in all public and private transactions.

Sixth: that to guard as far as possible against the counterfeiting, clipping, drilling, filing or defacing the coin, the dies with which the rupees are to be struck be made in future of the same size as the coin, so that the whole of the inscription may appear upon the surface of it, and that the edge of the coin be milled.

Seventh: that persons detected in counterfeiting, clipping, filing, drilling or defacing the coin be committed to the criminal courts and punished as the law directs.

Eighth: that all the officers, gomestahs and others employed in the collection of the revenues, the provision of the investment, and manufacture of salt, and all shroffs, podars, zemindars, Talookdars, farmers and all persons whatsoever, be prohibited affixing any mark whatsoever to the coin, and that all rupees so marked be declared not to be legal tender of payment in any public or private transaction, and that the officers of Government be directed to reject any rupees of this description that may be tendered at the public treasuries.

Ninth: that as there may not be a sufficient number of sicca rupees in circulation in some districts (notwithstanding the great number of this species of rupee that has been lately coined in the mints at Dacca and Calcutta) to enable the landholders to pay their revenues to Government in sicca rupees as stipulated in their engagements for the decennial settlement, that the various species of rupees current in the several districts be received at the public treasuries from the landholders and farmers in payment of their revenue until the 30th Chyte 1200 Bengal style, or 10th April 1794, at fixed rates of batta to be calculated according to the difference of intrinsic value which the various species of coins in circulation bear to the sicca rupee as ascertained by assay in the Calcutta mint.

Tenth: that all rupees excepting siccas, which may be received at the public treasuries agreeably to the ninth article be not on any account issued therefrom, but that they be sent to the mints and coined into siccas of the 19 sun.

Eleventh: that after the 30th Chyte Bengal style, corresponding with the 10th April 1794, no person be permitted to recover in the Dewanny or Maul Adawlute established in the provinces of Bengal, Behar and Orissa, any sum of money under a bond, or other writing, or any agreement written or verbal, entered into after the above mentioned date, by which any species of rupee excepting the sicca rupee of the 19 sun is stipulated to be paid.

Twelfth: that persons who shall have entered into bonds or writings or other agreements written or verbal, prior to 30th Chyte 1200 Bengal style, corresponding with 10th April 1794, whereby a sum of money is to be paid in any other species of rupee excepting the 19 sun sicca, and who shall not have discharged the same before that date, be at liberty to liquidate such engagement either in the rupee specified therein or in the 19 sun sicca rupee at the batta which may be specified in the table mentioned in the 9th article.

Thirteenth: that all engagements hereafter entered into on the part of Government for the provision of the investment or manufacture of salt or opium, be made in the sicca rupee, and that all landholders and farmers of land be expressly prohibited from concluding engagements with their under renters, ryots or dependent talookdars, after 30th Chyte 1200 Bengal style, corresponding with the 10th April 1794, excepting for sicca rupees, under the penalty of not being permitted to recover any arrears that may become due to them under such engagements as prescribed in the 11th article.

 

The low production of silver coins caused the date for the introduction of this regulation to be moved to 1795 [27]:

 

The Governor General in Council, taking into consideration the above letters, observes that similar representations have been received from other parts of the country of a want of a sufficient number of the nineteen sun sicca rupees, to make them the only legal tender of payment, and as the attempting to enforce this part of the regulations until a sufficient quantity of that species of coin has been introduced into the circulation, would be the source of much inconvenience and oppression to individuals, he resolves to postpone to the 10th April next the operation of that part of the thirty fifth regulation passed in 1793, by which the receipt of any rupees  excepting siccas of the nineteenth sun is prohibited from the 10th April last, and that in the meantime rupees of sorts be received in payment of the public revenue under the rules which were in force prior to the last mentioned date.

 

Attribution of the Type 1 Rupees to a Date

The silver coins produced during the 1790s are recorded by Pridmore, and consist of three types shown in the pictures below.

One point that needs to be considered in assigning the type 1 rupee to its date of issue, is the statement from the records, cited above, that a trial of laminating and cutting machinery was undertaken in the Calcutta mint in 1792 and that this trial resulted in the production of approximately 1000 rupees of slightly greater diameter than usual. The type 1 rupees would seem to be likely candidates for this experiment. Pridmore assigned these coins to trials undertaken in 1790, and it is possible that that is when these rupees were produced. However, the records strongly point to the fact that the Calcutta mint concentrated on producing the 19 sun dump rupees right up until 1793. The type 1 rupees are rare but not extremely so, which might fit nicely with a trial output of 1000 coins. Measuring the diameter of a few of these rupees gave the following results: Type 1 average diameter was 29.7 mm; Type 2 average diameter was 29.5 mm; and Type 3 average diameter was 26.7 mm

 

 4.10

Type 1: Broad rim, Hijri date 1202 (actual size)

 

 4.11

Type 2: Narrow rim, Hijri date 1202 (actual size)

 

 4.18

Type 3: Narrow rim, no Hijri date (actual size)

 

From these results, it seems reasonable to conclude that the type 1 rupee can be attributed to this event in 1792, and not to the 1790 experiments. The type 2 coins were probably produced from the middle of 1793 until the middle of 1794, when the type 3 coins began to be produced. This last type continued in production until 1818.

 

Copper Coins

Although the preparation of a new copper coinage had been discussed on and off for a number of years, the mint was preoccupied with producing sufficient gold and silver coins to standardise the coinage of the Presidency. It was not until 1794 that the assay master at the Patna mint started to agitate for a copper coinage (see chapter 5), and serious consideration was given to the matter.

In 1795, the Governor General, Sir John Shore, considered the matter in some detail. He started by blaming the shroffs for taking advantage of the situation [28]:

 

The present very defective state of the copper coinage has long been a subject of general complaint, but particularly amongst the lower orders of the people, on whom it occasionally operates as a heavy grievance...

…This constant fluctuation in the value of the copper coin, is a source of great profit to the shroffs who combine to raise and fall the value of it in the different parts of the country, buying it up when they have depreciated it, and selling it at an enhanced value when they have accumulated so large a quantity as to render the remainder in circulation at the places to which their influence may extend, insufficient for the dealings of the inhabitants. Exclusive of this source of advantage, they likewise derive a large profit from trafficing with the numerous sorts of old and counterfeit pice which have local currency in the different parts of the country in the same manner as by the exchange of the old copper.

 

Shore then went on to explain how the copper coinage had been operated by previous administrations:

 

Previous to stating any propositions for a new copper coinage, it may be necessary to notice the principles upon which the copper currency was regulated under the native administration and the rules that have been prescribed regarding it by the British Government.

Under the Mogul administration the silver coin was the only measure of value, and legal tender of payment. Gold mohurs and pice were struck at the mint for the convenience of individuals who carried gold or copper to be converted into those coins. But the Government never fixed the number of pice which should be considered as equivalent to a rupee, any more than the number of rupees that should pass in exchange for a gold mohur. Like other commodities, the gold and copper coins were left to find their value in the market, compared with the common standard of valuation, the rupee.

As a necessary consequence of the above principles, the quantity of copper contained in the number of pice exchangeable for a rupee, was in general nearly proportionate to the price of copper in the market, or in other words, the nominal and current value of the coin was nearly the same as the intrinsic value.

From the year 1772, when the mints at Patna and Dacca and Moorshedabad were withdrawn, no pice were coined in the provinces until the year 1783, when a contract was concluded with Mr Prinsep for coining pice on account of Government…

Next he discussed the requirements for the new copper coinage:

 

…The desideratum in the copper coinage of this country, is that a given number of the coin should pass universally for the fractional part of a rupee, or perhaps half a rupee or eight annas, and no more, in all purchases or payments whatever. To effect this desirable object, the following appear to be the principles on which the copper coinage should be regulated.

The intrinsic value of the coin should be nearly equal to its nominal worth estimating it according to a moderate average price, so as to preclude individuals from deriving any advantage from counterfeiting the coin. This is the great evil to be avoided, but which would be the necessary consequence of estimating the copper at too high a value and prevent the coin being generally received at its fixed value. On the other hand, supposing the copper be rather under valued, it can only produce the effects of occasioning some of it to be milled down when particular circumstances may cause an unusual rise in the price of copper. This however can rarely happen to any great extent; at all events it is an evil of comparatively little importance, being attended in its consequences only with the trouble of throwing a further quantity of the coin into circulation, the additional quantity of copper required for which can always be imported with advantage from Europe.

 

The type and cost of copper was considered:

 

The sheet copper is the proper sort of copper for coining into pice. From the annexed statement it appears that the average price of this copper at the Company’s sales for the last ten years, is current rupees 46:1:1˝ per factory maund of sicca weight 72:11:7 to the seer. The price however has arisen at different times within the above period considerably higher and at the sales in January 1794 it was near forty eight current rupees.

As the basis therefore for calculating the intrinsic value of the coin, and fixing the proportion between that and its nominal value, it might not be advisable to assume a higher value than forty five current rupees.

 

He then calculated a suitable weight for a pice and half anna, concluding that this latter denomination would be too heavy for practical purposes and that the coinage should therefore consist of pice and half pice:

 

The factory maund contains 2880 sicca weight; supposing a pice to be struck weighing sixteen annas, it will consequently give 2880 pice to the factory maund. If these pice be valued at a quarter of an anna each, or sixty four for the sicca rupee, they will have a value in circulation of exactly forty five sicca rupees the maund, which will be sixteen per cent more than the intrinsic value of the copper, estimating it at the proposed price of forty five current rupees each factory maund.

This difference will be sufficient to cover the expense of the coinage, without a probability of any inducement being afforded to individuals either now or hereafter, to counterfeit the coin.

Pice therefore of the weight and issued at the value above specified, would be sixty per cent more in weight & consequently in value than the pice now issued at the same value.

A half anna pice of thirty two annas weight would be too heavy a coin for circulation, and any smaller subdivision of a rupee than a one hundred and twenty eighth part appears unnecessary, as in transactions in which a smaller sign of value are required, the cowries are invariably used throughout the country. It appears expedient therefore that there should be only two descriptions of copper coin, a whole and a half pice, the former to pass at the value of a quarter of an anna, & the latter at half a quarter of an anna.

There can be no objection to the receipt of these coins upon the ground of their being over valued in the proportion above stated, for altho’ it is necessary that the intrinsic and nominal value of gold and silver coin should be the same, the observance of this rule is not equally necessary with copper coin, especially when declared as hereafter proposed, to be current for the fraction of half a rupee only. There can be little doubt therefore that under proper regulations, pice and half pice of the weight, and issued at the value above proposed, would be received throughout the country, at that value, and consequently remove the cause of the heavy grievance above complained of by the furnishing a convenient circulating medium for the petty transactions of the lower orders of the people, which will exempt them from the impositions they now suffer from the money changers.

 

The Governor General then went on to lay out proposed regulations for the copper coinage. Firstly he set out what the coin should look like:

 

These regulations are in abstract as follows:

That people in all parts of the country may be apprized of the value at which the coin is issued by Government, & to be received and paid by the public and by individuals, the value should be inscribed on one surface of it in the Persian, Bengal and Nageree, the three characters used in business in the different parts of the provinces.

 

Secondly he proposed that copper coins should only be accepted in payments of up to half a rupee (eight annas) in value:

 

Instead of obliging individuals to receive copper to the amount of one per cent as at the last coinage [i.e. Prinsep’s copper coins, see chapter 3], the coin should be declared a legal tender of payment for the fractional parts of half a rupee, or eight annas, and no more, & all the offices of Government should be prohibited receiving or issuing any larger amount in copper, in receipts and disbursements made on the public account.

 

Thirdly, coinage would be confined to the Calcutta mint:

 

As the coin is to be made on account of Government, it should be struck at the Calcutta mint, and not at the three city mints. The Calcutta mint will always be able to furnish a sufficient quantity of the coin for circulation, and by confining the coinage to this mint, Government themselves will be able to regulate the issue of it in proportion to the demand for it in the country.

On the preceding regulation it may be observed that no estimate can be formed of the probable extent of the demand for the new pice, as there are no data for calculating the quantity of old pice of various sorts now current, and supposing it could be ascertained, it would be no criterion for judging of the quantity of new pice that may be required for the circulation of the country, should they become generally current.

 

He then discussed the method by which the coins would be put into circulation:

 

To facilitate the introduction of the new pice, and to prevent any inconvenience arising from withdrawing the old pice from the circulation, a quantity of the former should be prepared previous to the publication of the intentions of Government to establish the new coinage, & sent to the General Treasury, the collectors of the revenue, the commercial residents, the salt agents and the collectors of the Government and Calcutta customs, with directions to dispose of them at the rate of 64 whole pice or 128 half pice for the sicca rupee, to any persons who may be desirous to purchase them at that rate. These officers however should be prohibited from receiving in any payment which may be made to them on the account of Government, or issuing in any public disbursement, a greater sum in pice than the fractional parts of eight annas in each receipt on payment.

When any of the officers above mentioned shall have occasion for a supply of pice for the circulation, they should apply for them to the Governor General in Council through the regular official channel, submitting at the same time the grounds of the application. They should at the same time be enjoined to be particularly careful not to dispose of them to the shroffs in large quantities so as to enable them to derive an advantage from the sale of them, but to endeavour to distribute them as much as possible throughout their respective district to persons who may have occasion for pice for their private disbursements, and not to make a profit by disposing of them.

 

Next he discussed receiving old pice into the treasuries and, interestingly, refers to “Calcutta pice” as well as “Prinsep’s pice”. Presumably these “Calcutta pice” are the rare coins with the mint name ‘Kalkutta’ (see chapter 2, Cat. Nos. 2.197 to 2.199):

 

As Government cannot in justice refuse to receive the Calcutta pice at the rate at which they issued them, an opportunity should be offered to individuals who may have them in their possession, to obtain the full value of them. For this purpose a notice should be published that they will be received until the [……..] at the General Treasury and the treasuries of the collectors at the rate of eighty sicca rupees the maund of eighty sicca weight to the seer, to any amount in discharge of sums payable to Government, or if tendered by persons not having payments to make the public, that they shall receive in exchange rupees or gold mohurs or pice of the new coinage. But the officers above mentioned should be enjoined to be careful not to receive under this publication, any of the counterfeit pice which are known to be in circulation, or indeed any other pice than the Calcutta or Prinsep’s pice.

After the period specified in the preceding article, neither the old Calcutta pice mentioned in the 5th article, nor any other pice (excepting the new pice) should be received at any of the public treasuries or offices, or issued therefrom on any account whatever, nor should they be legal tender of payment for any sum in any public or private transactions.

All public officers should be prohibited issuing the old Calcutta pice prior to the date above-mentioned, whenever they have a sufficient quantity of the new pice to issue in payment of the fractional part of eight annas.

The old pice which may accumulate in the public offices in consequence of the preceding orders should be sent to the Calcutta mint and coined into new pice.

It may be likewise necessary, to prevent the counterfeiting or defacing the coin, that persons convicted of such will be committed to take their trial before the criminal court and punished as the law may direct.

By the adoption of the above rules, the old pice will be withdrawn from circulation without inconvenience to the public and the new pice be gradually introduced, and in such quantity only as the circulation may require.

 

He then went on to consider the costs involved:

 

From the annexed statement furnished by the sub-treasurer, it will appear that the value of the Calcutta pice issued by Government, estimating them at the rate of eighty sicca rupees the maund, amounts to sicca rupees 374253:13:6. It is to be presumed that a considerable part of them have been lost or carried out of the country. But supposing the whole quantity to be returned upon the hands of Government, the loss will be inconsiderable when compared with the relief which the new coinage will afford to the lower classes of the people. The pice which may be paid in, when melted down and converted in the new coin will produce about half the amount of value at which it will be received, and it is to be recollected that in the first issue, Government derived a profit of thirty three per cent, which will reduce the ultimate loss upon the whole coinage, supposing what is extremely improbable, all the pice to be paid in, to rupees 93,563.

This sum might be further reduced by instructing persons in the different parts of the country to purchase the Calcutta or Prinsep’s pice on account of Government, provided they can procure them at a low value, nor could the measure be considered as an injustice to the public, as all persons who may be in possession of any of these pice are at liberty by the rules above proposed to pay them into the public treasuries at the full value at which they were issued by Government. The Board however will hereafter take into consideration the propriety of adopting this measure should circumstances appear to require it...

 

In accordance with this resolution, James Miller, the mint master, prepared specimens of whole and half pice [29]:

 

I have the pleasure to send you herewith four specimens of each of the copper coins, as directed in your letter of the 2nd ultimo, for the inspection of the Honble Board.

 

In November 1795, the Governor General approved the coins and instructed the mint master to begin production:

 

I am directed to acknowledge the receipt of your letter of the 6th instant and to acquaint you that the Governor General in Council approves of the samples of the whole and half pice which you have submitted and desires that you will make the necessary preparations for the new copper coinage with all practicable dispatch.

You are to coin an equal value of the whole and half pice until it shall be ascertained which of the two coins are likely to be in the greatest demand for circulation, when the future proportions of each may be regulated accordingly.

The Board of Trade have been directed to allow you to examine the sheet copper in the Company’s warehouse and to retain from the quantity now in store, and the expected imports of the current season, three thousand factory maunds of the sort which you may select as most proper for coining into pice.

 

These first specimens probably had the inscriptions ek pau anna (a quarter of an anna) and nīm pau anna (half a quarter of an anna) because the Governor General agreed that this should be changed [30]:

 

The Governor General in Council understanding that the relative value of the whole and half pice with respect to the sicca rupee will be better understood by the natives in General and especially the lower orders of them, by substituting ek pai sicca (one pice sicca) and adh pai sicca (half a pice sicca) for ek paow anna (a quarter of an anna) and neem paow anna (half a quarter of an anna), the inscription ordered on the 2nd ultimo, resolves that instructions be issued to the Mint Master for that purpose.

 

The method of producing copper coins was found to be more difficult than first envisaged [31]:

 

In the idea that the copper pice of which I transmitted samples to Mr sub secretary Barlow on the 6th instant will probably be approved by the Honble Board, I directed some questions to the Foreman respecting the apparatus that would be necessary for melting down about 215 maunds of old pice which have been received from the general treasury and for recoining the same into new pice; in answer to which I have received his observations thereon, which are as follows:

The natives cannot melt copper sufficiently malleable to be made into pice. It has been tried repeatedly but found not to answer either for the hammer or laminating machines.

The best and least expensive mode of making the new pice is from sheet copper, by the laminating machine. The braziers will (I believe) give something more for the cuttings than for sheet copper as the former saves them the trouble of cutting the copper to put into their pots when they make brass. Mr Prinsep found this to be the case when he made pice.

The Durapps can cut down the old pice so as to answer for the new, but that is a tedious mode.

 

In the same letter, the mint master found that he could get useful information from some of the mint workers who had formerly been employed by Prinsep:

 

I have since enquired of some of the natives in the mint, who I learn had formerly been employed by Mr Prinsep, and each of them corroborates the report of the foreman, that old pice cannot be melted down sufficiently malleable for the purpose of forming new ones, in which case I conceive it would be necessary to make use of sheet copper from the import warehouse.

It seems however necessary that whatever may become of the copper of the old pice they cannot be disposed of in their present form without again forcing themselves into some degree of circulation, and that for this reason the old pice should either be melted down or in some other manner so effaced that they cannot pass as coin either of standard or of inferior valuation.

In regard to the cutting down of the old pice by the duraps, I am induced to believe that if at all practicable, the expense and delay would both be beyond all reasonable proportion, for exclusive of their being able to form but a few in that way, if all of them were so employed, they could only work upon them during the short time that may happen when neither gold nor silver happens to be in the mint. Besides which considerations it is only the old whole and half pice that could be so cut down, all the smaller old pice being of less weight than the new ones.

If therefore the Honble Board should approve, I would recommend a supply of one or two hundred maunds of sheet copper from the Import Warehouse, that in this case I may lose no time in providing the additional servants and laborours necessary for forming the new pice by the laminating machine, and in the meantime the old pice can remain locked up in the mint until the best mode of disposing of them may be determined on.

 

The mint master was ordered to make the new copper coins from sheet copper, and to dispose of the Prinsep’s and Calcutta pice in a way that would mean they could not be used as coin:

 

Ordered that the Mint Master be directed to coin the new pice and half pice from the copper which may be obtained from the import warehouse and to melt down the Prinsep’s or Calcutta pice which were sent to him from the general treasury, or cut or deface them so that they cannot be introduced again into circulation as coin, and to dispose of the metal or the cut or defaced pice to the best advantage.

 

and he sent examples of the sheet copper that he considered appropriate for coinage, asking that it might be sent out from England in sheets one foot square [32]. A little later he revised this and sent another sample of the copper required [33].

However, even once the mint master got the sheet copper from the Import Warehouse Keeper, he found that the cost of producing the coins was much greater then he had anticipated. The copper was valued at Rs 5,460-3-2 and produced Rs 5,394-8-9 worth of coins, amounting to a loss of Rs 65-10-5. In a second experiment there was an even greater loss and the only solution that he could identify was to reduce the weight of the coins [34]:

 

…If the new whole pice were reduced to the weight of 12 annas each, and the half pice to six annas, they would still weigh 20 per cent more than Mr Prinsep’s pice, for thirty-two of Mr Prinsep’s whole pice were valued by Government at a rupee, or half an anna each, and when struck were intended to weigh but 1 rupee 4 annas, which at the most gives 40 sicca weight per rupee. Whereas if the new whole pice, valued only at one quarter of an anna each, were reduced to the weight of 12 annas, and the half pice in proportion, the publick would receive 48 sicca weight per rupee in 64 whole pice, or 128 half pice, of better copper and more complete manufacture.

 

In April 1796, the Governor General agreed that an experimental coinage should be undertaken to see what the lower weight coins would look like [35]:

 

Ordered the Mint Master be informed that the Governor General in Council desires he will coin as a specimen a small quantity of the whole pice at the reduced weight of 12 annas, instead of 16, and the pice at 6 annas instead of 8, and that he will submit a particular account of the expense…

 

And a few days later the specimens were duly submitted [36]:

 

…I herewith beg leave to submit musters of whole and half pice, weighing 12 As and 6 As each, respectively…

 

The lower weight coins were approved, but at the same time the Calcutta Government resolved to ask London if it might not be better to obtain the required copper coins from England. Nothing came of this request and copper coins continued to be produced in the Calcutta mint. At the same time, the sub-treasurer was instructed to return the coins coined so far, to the mint, so that they could be recoined into the new, lower weight, pice [37].

Unfortunately the mint did not have the technical ability to re-coin previously minted pice, nor could they re-coin the older Prinsep’s pice as discussed above, but reiterated yet again [38]:

 

…I however beg leave to represent that I have found it no less impracticable to recoin the new pice lately formed than it was to recoin the old pice of Mr Prinsep.

I likewise understand that the labour and consequent expense of defacing them so as to admit of them being sold as copper in the bazar, without danger of being used as coin, would amount to a very considerable proportion of their value, and that melting would be equally ineligible by reducing the value of the metal for common purposes, exclusive of the expense of servants, firewood etc and injury to the furnaces.

From all that I have been able to learn on the subject, the best method that occurs, if it shall be found practicable, would be to deliver over both the old pice of Mr Prinsep, and those lately formed weighing 16 and 8 annas, to the Commissary of stores to be applied to the making of brass, for ordnance. In which case probably the small pieces into which the copper is divided might render it no less eligible for the purposes suggested than if it were in the sheet.

 

The smaller half pice proved problematic. The impression did not always show up clearly and the mint master investigated various reasons, finally concluding that it was the thinness of the metal used, that caused the problem [39]:

 

Having observed about the beginning of the present month, that the impression of the half pice was in several instances, so faint as not to be distinctly traced on the face of the coin, I minutely enquired into the cause, in the idea that it might have proceeded from striking off too many pieces with the same dies, from carelessness in the dye feeders and lever men, or from both these causes.

I found however that the foreman chiefly ascribed the imperfection to the thinness of the copper from the reduced weight from eight annas to six annas, and in consequence I had assented to his reducing the cutters so as to render the half pice blanks somewhat thicker. A few maunds of this sort were actually struck off, but as some parts of the letters of the dye did not come within the edge of the coin, I was admonished that it would be considered a palpable defect, and I therefore put an instant stop to this coin, nor has a single piece of it been yet sent to the Treasury, nor will any be sent thither unless from the difficulty attending the formation of this small pice, they should be admitted of by the Honble Board.

I desired to know from the foreman whether new dyes could be made for the half pice, of such diameter as would admit of a deeper and more distinct impression, and I now beg leave to enclose copy of his answer with the inscription he suggests, and from which the whole of the Nagry characters are left out.

I should have thought it altogether unreasonable to have expected the same precision as to the formation and weight of copper pice that would be indispensable in either gold or silver, but I considered that all pice where the difference of weight should exceed one anna in twelve (or above 8 per cent), and whose circular form was rendered irregular by coiners, ought not to be considered as falling within the difference that might be admitted between the precision requisite to the gold and silver coin, when compared with the copper, and that such defects indicated carelessness in the workmen.

But though the pice which have been coined contain more samples of this sort than I could wish, I do not mean to trouble the Honble Board with any such, unless they should be called for, as I have no other wish or object than to render the pice as nearly as practicable, equal to the musters which were delivered in to the Honble Board with my address of the 13th April last, not doubting that every indulgence will be granted to such imperfections as are unavoidable.

The points of present consideration however, seem to be confined solely to the half pice of six annas

1st, whether the Honble Board shall think proper to continue them of their original size, agreeably to the enclosed sample of the general run of that coinage, marked No 1, notwithstanding the faintness of the impression.

2nd, whether six anna pice of reduced size, but struck with the same dies as per the enclosed sample, No 2, would be admissable or not, and

3rd, whether such alteration in the inscription as sent in by the foreman can now be adopted with advantage and propriety

 

The Governor General ordered the mint master to reduce the diameter of the half pice and, if this did not work, to prepare new dies; and, if the whole inscription would not fit, then to remove the Persian rendition of the value, leaving only the Nagri. Once this had been addressed, the mint master was instructed to strike the copper coins in the proportion of 350,000 whole pice to 150,000 half pice [40]. Finally, in July 1796, he was told to concentrate on the production of whole pice, and not to produce half pice, which he had not done up to that point, except as trial runs [41].

By August 1796, the attempts to produce pice of 16 annas weight had resulted in a total production of 363,000 pieces of whole pice and 642,992 half pice. These had all been sent to the treasury, but could not be issued because the lighter weight pice had by then been produced and issued. These amounted to 1,226,000 whole pice and 605,000 half pice (despite the fact that he had been told not to produce half pice) [42].

By October, all of the copper available had been converted into coins [43] and it only remained to find a way of disposing of the sizel (copper scrap) left from the coinage, and all of the heavy-weight pice that had been struck initially. All of this was eventually sold as scrap [44].

Further coinages of copper took place in December 1800 [45], May 1801 [46] and October 1801 [47].
