50 Dinar - Naser al-Din Qajar

Naser al-Din Shah's reign of nearly half a century was the longest of any Qajar ruler, and the copper coinage issued under his name reflects the monetary disorder that plagued it. Iran operated without a unified mint system for much of this period, with coins struck at provincial centers including Tehran, Tabriz, Isfahan, and Rasht — each producing work of inconsistent quality and occasionally divergent weight standards. Attribution to a specific mint often requires die study rather than legible mint marks.

The Shah was assassinated in 1896 by Mirza Reza Kermani, just days before the celebration of his fiftieth year on the throne.
