1 Dinar - 'Izz al-Din Mas'ud I

Mas'ud I ruled Mosul as a Zengid atabeg under the shadow of Saladin's expanding Ayyubid power — a political reality that shaped nearly every administrative decision of his reign, including coinage. The Zengids of Mosul retained nominal independence through careful diplomacy rather than military resistance, and their gold issues reflect a court still projecting authority it was increasingly obliged to negotiate.

Album 1862 places this type within a tightly defined sequence for the Mosul mint, which remained one of the more active northern Jaziran production centers through the late 12th century.
