I wish that finding the attribution of this coin were easier.
Here is the problem.
The sultans of Malwa, at least from 1468 to 1500 (Ghiyath Khalji), 1500 to 1510 (Nasir Shah) and 1511 until 1531 (Mahummud Shah II) (dates get difficult after that due to invasions) produced, in some respects, similar coins. Generally, all proudly proclaim that they are the Sultans who are sons of Sultans. The dates indicated on the coin may not correspond to the actual date of mint.
I was able to locate examples of coins in the reign of Ghiyath and Mahummud Shah II that depict dates in a very similar way, as is the case in this coin. The examples of Nasir's coins that I have seen look a little different than his father's or son's.
The likelihood is that this coin was minted in the reign of Mahummud Shah II, even though the date would suggest an earlier reign; 916 or 919 would fall within the reign of Nasir Shah. Indeed, I found one coin attributed to Mahummud Shah II that had the date 919AH (1505AD?) in the Fitzwilliam collection.
