Tetrobol

Gambrion was a minor Mysian city of uncertain foundation, likely a Lydian-era settlement absorbed into the Persian satrapal system before asserting its own civic coinage during the fifth and fourth centuries BC. Its output was modest by any measure — the city never commanded significant regional weight — which is precisely why surviving specimens are catalogued as varieties rather than established types: the dies were few, short-lived, and inconsistently reproduced. The Winterthur 2 and SNG France references diverge on specifics, suggesting more than one obverse or reverse pairing was in active circulation simultaneously.
