1 Qiran - Naser al-Din Qajar Tehran

Naser al-Din Shah's monetary reforms of the 1870s attempted to impose standardization on a coinage system that had operated through a fragmented network of provincial mints for decades. By consolidating production at Tehran, the central government sought tighter control over silver content — a persistent problem, as regional mints had long been accused of debasing issues to local advantage. The qiran denomination itself had been fixed as the backbone of the reformed rial system introduced in 1876.
