1 Fals - Jahwar ibn Marrar al-'Ijli

Al-Rayy, located near modern Tehran, was one of the most productive copper-fals minting centers of the early Abbasid period, yet attribution of individual city governors' issues remains contested among Islamic numismatists. Jahwar ibn Marrar al-'Ijli governed the region during the turbulent transition years following the Abbasid revolution of 750 — a coup that swept away Umayyad administrators and installed new provincial authorities with considerable speed, leaving many local mint operations in a state of administrative flux for years afterward.

Copper fals of this period circulated almost exclusively at the hyper-local level, rarely traveling beyond a single city's markets.
