Fath Khan bin Firoz Tughluq Billon 1 Tanka Delhi Sultanate 1358-1359 CE

Obverse: Fathkhan firuz shah jall allah zillalahu jalalahu

Reverse: Fi-zaman al-imam amir al-muminin abi abd allah khulidat khilafatuhu

Fath Khan, the son of Sultan Firuz Shah Tughluq, briefly issued coins during his father’s reign around AH 759–760 (1358–1359 CE), hinting at a proposed succession or a symbolic co-regency. Firuz Shah, known for his architectural works and administrative reforms, favored dynastic continuity, and Fath Khan was likely positioned as heir. His rare billon Tanka, weighing 8.89 grams, bears his name and religious titles, while the reverse praises the reigning Caliph, aligning with traditional Islamic legitimacy. The coin reflects both paternal patronage and political aspiration. Though his rule was short-lived, this coin remains a scarce testament to his fleeting historical presence.
