Qanhari Dirham 'Damma' - Uyayna ibn Musa al-Tamimi

Uyayna ibn Musa al-Tamimi governed during the chaotic opening years of Abbasid rule, when the new dynasty was still consolidating power after overthrowing the Umayyads in 750. The 'damma' — a fractional denomination far below the standard dirham — served local exchange in eastern markets where full dirhams were too valuable for everyday transactions. Qanhar itself remains imprecisely located, which is part of why attributing these tiny pieces took so long in modern scholarship.

At 0.32g, the flan is almost absurdly small, and die alignment on surviving examples is rarely consistent — not a production flaw so much as an inherent limitation of striking fractions at this scale.
