1 Tanka - Firuz Shah Tughluq

Firuz Shah Tughluq's coinage policy was deliberately conservative — he maintained the billon tanka at a time when his predecessor Muhammad bin Tughluq had destabilized the currency through a disastrous token coinage experiment in the 1320s and 30s, flooding the market with brass and copper pieces that the public immediately began counterfeiting. Firuz's long reign allowed the Delhi mint system to restabilize, and his issues circulated across a sultanate that, while contracting at the edges, remained administratively coherent through the 1370s.
