The auction house notes that the coins may have been struck at a travelling mint that accompanied the caliph. Since the reverse die bearing the date was also used in Damascus at some point that year, “it cannot have been in use at a location away from the capital for more than a few months at most,” according to the lot description.
Scholars have suggested some connection between these coins and the Hajj pilgrimage.
“The [coins] remain some of the most hotly-debated and historically significant of all early Islamic coins, and we are delighted to be able to offer such an exceptional piece in our April sale,” Lloyd said.
The April 10 sale will also include a unique early Umayyad silver dirham from the unrecorded mint of Tukharistan, as well as Abbasid gold dinars and Fatimid coins from Palestinian mints.
