Qanhari Dirham 'Damma' - Abu Mansur

The Qanhari dirhams of Sind represent a localized silver coinage that persisted through the Arab administration of the lower Indus region long after the Umayyad and Abbasid caliphates had moved on to heavier, more standardized issues. The "damma" denomination — a term derived from the Arabic daniq — circulated as fractional currency in a region where trade with inland merchants demanded small-denomination silver. Abu Mansur's issues fall within the period when Mahmud of Ghazni was conducting his repeated campaigns into the subcontinent, a pressure that almost certainly disrupted local mint continuity.
