I was told that this is the first issue in the name of Shah Jahan minted at Ahmedabad. AH 1037, RY 1 instead of Ahd as is normal on most Mughal coins. Another difference, I was told, is that for this type, coins have legend in 4 lines and the AH date is written out in the last line while this coin has the legend in 3 lines and the date is in the central line.
Please help.
