Qandhari Dirham 'Damma' - Umar II bin Abdullah

The "Qandhari" designation points to the Kandahar-influenced Arab-Sasanian monetary tradition that persisted in Sind long after the Abbasid caliphate had standardized coinage elsewhere. These fractional silver pieces — the damma being a subdivision of the dirham — circulated in a region where the Arab governors operated with considerable autonomy from Baghdad, maintaining local denominational conventions that the broader Islamic world had largely abandoned by the tenth century.
