Shahjahanabad coin is usually found in Badre Munir couplet, while this one is
issued in his full name and title which is very rare to find and very few
specimen are known. But this particular specimen has Regnal year '2' engraved
over 'Ahd' which to the auctioneer's knowledge is the first piece known.
It can possibly have 2 explanations.
First Aurangzeb had 3 coronations, and the second the year changes and die is
not worn out so instead of making a new reverse die, the engraver engraves 2
over Ahd in the same die.
