5 Rials - Rezā Pahlavī

These coins were struck during Reza Shah's aggressive modernization campaign, which included replacing the traditional Iranian monetary system with a decimalized one anchored by a new national bank — Bank Melli Iran, established in 1927. The large silver issue was part of a deliberate effort to project state authority through coinage at a moment when Reza Shah was simultaneously abolishing regional power structures and suppressing tribal autonomy.

Production ran only four years before the denomination was discontinued, likely a casualty of global silver price instability following the Great Depression. Circulated examples are common; uncirculated pieces with full luster are substantially harder to locate than mintage figures alone would suggest.
