Letter from A Beaumont (Calcutta Mint Master to Bengal Council, dated 21st November 1763

According to your orders, I herewith deliver in, a statement of the mint from the time that office has been under my direction, an account of the mint charges with the duty and custom received on coinage, likewise an account of what treasure has been coined on account of the Honorable Company, by which they will see at one view the whole advantages that have accrued to them by their mint at Fort William, over and above the coinage of their own treasure, for which no charge has been made. In answer to the 35th paragraph of the General Letter, I must beg leave to assure you that the mint has ever commanded my strictest attention, but (as the Honble Company have been before advised) for want of proper materials and utensils, assays cannot be made with the greatest accuracy, but the strictest care has been ever had to keep the Calcutta rupee up to the same weight and fineness as what are coined in the mints at Moorsheedabad and Mongheer. The small deficiency in the weight of the Arcot rupee may have been occasioned by the air affecting the balance at the particular time of weighing those rupees sent home, but cannot be general, as, from the manner of delivering money from the mint, which is by weighing one hundred rupees at a time in the most exact scales that can be made in this country, if every rupee was deficient even so small a fraction, it would be evident & be too considerable not to be complained of. I cannot help observing the great difference of the assay of the rupees sent by the Hawke, as the Calcutta sicca rupees as well as the Calcutta Arcot rupees were coined under my immediate inspection, and the Calcutta sicca rupees were all coined from ingots of silver of one and the same melting. The Calcutta Arcot rupees were likewise coined out of ingots of silver one and the same melting, of that standard, so that I cannot comprehend how so great a difference can arise as appears by the reports from the Tower.
