Watch List notes:

UMAYYAD, TEMP. HISHAM (105-126h), Dirham, al-Mubaraka 117/9h. Obverse: In margin: unit of date lacking a fourth 'tooth'. Weight: 2.64g Reference: cf Klat 575. Fine, an unusual engraving error. The unit of the date on this coin is missing a 'tooth' and so is ambiguous. The three remaining 'teeth', however, are consistent in height and clearly denote the letter 'sin', and it appears to be the higher 'ba' which has been omitted from the die. Such engraving errors are very uncommon and of considerable interest.
