1 Tanka - Fakhr-ud-din bin Muhammad Tughluq

Fakhr-ud-din was a regional rebel governor who briefly controlled Bengal and struck coins in his own name during the mid-14th century, exploiting the instability that plagued Muhammad bin Tughluq's reign — a sultanate so administratively overstretched that provincial breakaways became almost routine. The billon composition reflects Bengal's chronic silver shortage during this period, not a central mint decision.
