Dinar - Rukn al-Din Baybars II al-Qahira

Baybars II ruled for less than a year — from April to June 1309, depending on the source — before being deposed and executed by the restored Nasir Muhammad ibn Qalawun, who had himself been overthrown to make way for Baybars in the first place. The brevity of that reign makes any gold issue attributable to his Cairo mint exceptionally scarce by simple arithmetic of production time.
