Which Ruler and Mint?

A silver coin from India, Weight is 11.36 gms and Diameter is 26 mm, I'm guessing Tanka of Islam Shah Suri, but not sure, can't identify the Mint! Is this coin even rare, according to the condition? I'm thanking you all for going through this piece 🙏🏻.

I think your attribution is correct. Your coin appears to match this one

Sultans of Dehli, Islam Shah Suri, Gwaliar mint, Goron/Goenka D961A

I'm not able to read a date, but maybe another of our members can. 

You have really made my day, it's looking like the same piece, same mint, I bought this today for $28 and hope this is a good buy! Keep smiling and thank you again :)

On his silver coins, the name of Suri dynasty ruler in Devanagari ‘Sri Islam Shah’ [श्री ईसलम सह] is always present but in this coin, the name is quite imperfect, it is ‘Sri Islam Sa’ [श्री ईसलम स] written within the rectangular space in bottom, so isn't it a mistake and making the coin rare or unique among all the coins struck in the mint of Gwalior!
