1 Tanka - Shams al-din Yusuf Shah 4Chamber Type

Shams al-din Yusuf Shah ruled Bengal for roughly seven years before being deposed, a reign squeezed between the longer and better-documented tenures of his predecessors and successors in the Ilyas Shahi line. The four-chamber type represents a specific die arrangement used by the Bengal mint at Firuzabad during this period, distinguishing it from the more common single-field layout and making it a useful chronological marker for collectors working through the sultanate's coinage sequence.
