Following up on the excellent attribution by @maneeshks, I checked Goron/Goenka and found the match of a silver tanka of Ghiyath al-Din Bahadur (AH 720-724 = AD 1320-1324), mint Khitta Ghiyathpur, GG B105. Also found an example (struck with different dies that have slightly different engraving) on Zeno.
