Qanhari Dirham 'Damma' - Tamim ibn Zayd al-Qayni

Tamim ibn Zayd al-Qayni governed Sind during a period when Arab monetary authority over the conquered Indus territories was still being consolidated — the Qanhari dirham type, far lighter than standard Umayyad silver, reflects a deliberate accommodation of local exchange customs rather than an imposition of caliphal weight standards. These fractional pieces circulated alongside heavier Arab-Sasanian issues and indigenous coinage in a region where monetary unification remained politically inconvenient. The 'Damma' designation refers to a local unit of account, not a transliteration of any Arabic term, pointing to the depth of indigenous influence on even nominally Umayyad issues.
