1 Rial - Mohammad Rezā Pahlavī

By the time these rials were being struck, the Shah's government was accelerating an industrialization program so disruptive — compulsory land redistribution, forced urbanization, the dismantling of bazaar merchant networks — that it had alienated nearly every social class simultaneously. The coins were minted in the final two years of Pahlavi rule, making them among the last issues of a dynasty that had lasted just over half a century before the 1979 revolution terminated production entirely.
