Dirham - Anonymous al-Furat

The "Anonymous al-Furat" designation points to dirhams struck in the Jazira region — the upper Mesopotamian river country between the Tigris and Euphrates — where mint attribution remains contested among specialists. Abd al-Malik's monetary reform of 77–79 AH (696–699 CE) abolished the Sasanian-derived drachm types entirely and imposed a purely epigraphic silver coinage across the caliphate, making these among the earliest products of that standardization. The reform was as much an assertion of Arab-Islamic political identity against Byzantine and Sasanian numismatic traditions as it was a practical currency measure.

The al-Furat mint group is not fully resolved in the standard references, and attributions between Nahr al-Furat issues and neighboring provincial mints have shifted across successive scholarship.
