Leo III the Isaurian
The coin remained in regular issue under Heraclius's successor Constans II (r. 641–668), from whose reign many specimens survive, but becomes rarer for Constantine IV (r. 668–685), and thereafter seems to have been only occasionally minted as a ceremonial coin until Theodosius III (r. 715–717). In 720 Emperor Leo III the Isaurian (r. 717–741) issued a new silver coin, the "miliaresion".
