*Umayyad, dirham, al-Basra 100h, 1.47g, severely clipped and with a slot cut in the centre into which an additional piece of silver has been inserted, fine and unusual The practice of fixing an additional strip of silver into slits cut into the coin is normally associated with later Spanish Umayyad issues. The adjusted weight of the present piece is almost exactly correct for a half-dirham or, equally, for a contemporary European denier. (£50 - 100)
