Irregular AE - George IV Mule: obv - G.IV, rev - Tamar

The pairing of a George IV obverse with a Tamar reverse is a recognized mule type from the Georgian royal mint at a moment of dynastic transition — Tamar died around 1213, and George IV Lasha inherited a kingdom at its territorial peak. Whether this combination reflects deliberate reuse of existing reverse dies or a transitional production overlap is unresolved, but such mules from the Tbilisi mint are documented and not the product of later fabrication.
