50 Rials - Mohammad Rezā Pahlavī

Harrison & Sons had been printing Iranian banknotes since the early 1950s, when the relationship was formalized following the nationalization crisis and the eventual stabilization of the Shah's government after the 1953 coup. This particular series — issued across the early-to-mid 1960s — bridges the period between the White Revolution's announcement and its early implementation, when the regime was pushing land reform and modernization hard enough to require a broadly circulating low-denomination note trusted by a rural population.

Pick 73 is the second Harrison-printed 50 Rials type, distinguished from its predecessor by the Bank Markazi Iran imprint, which replaced the earlier Bank Melli issuing authority following the central bank's establishment in 1960.
