Æ20 - Trajan ΕΠΙ ΓΛΑΥΚΟΥ ΚΥΖΙΚΗ

The magistrate name ΓΛΑΥΚΟΣ (Glaukos) appearing on this issue places it within Cyzicus's local civic coinage, where named strategoi or grammateis served as the responsible authority — a Greek administrative tradition the city maintained well into the Roman imperial period. Cyzicus retained unusual monetary autonomy under Rome, having long operated a prestigious mint whose electrum staters circulated across the Aegean world for centuries before Augustus curtailed Greek civic gold. By Trajan's reign the city issued only bronze for local use, but the civic pride encoded in naming a magistrate remained.
