I have scrolled through thousands of pictures, many websites.
Coin details:
Diameter = 14mm
Thickness = 3mm
Weight = 3.6 gr
Silver in color
alloy = I am thinking it is Billon due to the green corrosion
Orientation = off by 90 degrees
What I will call the Obverse of this coin

Looks identical to:
1 Tanka - Firuz shah Tughluq Sultanate of Dehli
but the reverse is different and different specs
The Reverse:

Looks closest to (least the center does)
1 Tanka - Bahlul Shah Lodis Sultanate of Delhi
But the obverse is different and specs are different
Both coins referred to at located at this link:
