2 Rials - Rezā Pahlavī

Reza Shah's coinage reform of 1931 was part of a broader modernization drive that also abolished the old qiran system and pegged the rial to gold — a deliberate break from the monetary chaos that had plagued Iran under the late Qajars. These silver issues were struck at the Tehran mint during a narrow window before economic pressures and the global silver price collapse effectively ended large-denomination silver circulation coinage in Iran. The series ran only four years.
