Arab–Sasanian coinage is a modern term used to describe Islamic coinage struck in the style of the coinage of the Iranian Sasanian Empire (224–651) after the Muslim conquest of Persia, on behalf of the Muslim governors of the early Islamic caliphates (7th–8th centuries).
These coins, mostly silver dirhams but also copper coins, were struck in the historic Sasanian lands of Iraq and Iran, and continued to show the portrait of a bust of a Sasanian emperor as well as other non-Islamic motifs of Sasanian coins, alongside Arabic inscriptions.
