1/2 Drachm - Muqatil Abbasid Governors of Tabaristan - Arab-Sasanian

Tabaristan — the heavily forested region south of the Caspian Sea — resisted full Abbasid administrative control far longer than surrounding territories, and its semi-autonomous governors continued striking fractional silver in the inherited Sasanian style well after the conquest. The Muqatil governors used this coinage to maintain local economic continuity in a region where Iranian monetary conventions were deeply entrenched and Arab-weight standards would have been commercially disruptive.

Valentijn's Sn#80 classification places this among the later issues of the series, by which point Abbasid authority over the mint was nominal at best.
