Sultans of Delhi, Sikandar Shah Lodi, Tanka, G&G D706
The date is mostly off the flan at the bottom of the second photo but according to Goron & Goenka these were struck from AH 900-922 = AD 1495-1516.
Here's the Numista listing

though I see some of the manufacturing dates in the Numista listing are incorrect.
I have submitted corrections for this listing.
