The Hibari (or Habbarid) Dynasty which had become independent lasted from 855 to 1010 A.D. i.e. till annexation of Sindh by Mahmud of Ghazna, the coinage consists of tiny fractional darhams (called damma) poorly struck, at either Multan or Mansura (Mint not indicated on coins).
Damma weighs 0.5 grams traditionally used by the Gurjuras, Parharas, and other medieval Hindu Kingdoms. One damma corresponds to one sixth of a traditional Islamic darham. According to some numismatists Habbarid dynasty lasted from 257 to 400 AH (871 to 1010 A.D.).
