Qanhari Dirham 'Damma' - Mansur ibn Jumhur al-Kalbi

Mansur ibn Jumhur al-Kalbi governed Sind as an Umayyad appointee during a period of acute dynastic instability — his tenure overlapping almost exactly with the Abbasid revolution that destroyed the Umayyad caliphate in 750. Whether these fractional silver pieces continued striking after the Abbasid takeover, or were abandoned with the regime that authorized them, remains an open question in the numismatic record.

The "cf." qualifier against Album 1493 reflects genuine uncertainty: no clean type match has been established, and attribution rests on stylistic and regional inference rather than confirmed die correspondence.
