It is from the reign of Firuz Shah Tughlaq (also Tuglaq) from the Delhi Sultanate (reigned from 23 March 1351 – 20 September 1388 / AH752-790)
Coin diameter: 16mm
Weight: 3.59 ~ 3.60 grams
Material: I am told it is silver but cannot confirm that

There is a 1 Jital - Firuz Tughluq in the numista catalogue at https://en.numista.com/catalogue/pieces93267.html but that is different from this coin in size, weight and markings.
Please help me identify this coin (value-currency, year, material and reference).
Thank you in advance for your help
