Fals - Anonymous Isbahan

Anonymous copper fulus from Isbahan (modern Isfahan) occupy an awkward documentary gap in Umayyad monetary history. The great silver and gold reforms of Abd al-Malik in 696 AD standardized the caliphate's prestige coinage, but copper remained largely unregulated — struck by local authorities with no centralized weight standard, which explains the wide mass variation seen across surviving specimens of this type.

Isfahan itself was a former Sasanian administrative center, and early Umayyad copper at this mint often shows transitional borrowings from pre-Islamic provincial coinage practices.
