Æ26 - Caracalla ΕΠΙ ΚΟΔΡΑΤΟΥ ΑΡΧ ΚΟΤΙΑΕΩΝ

Cotiaeum, modern Kütahya in western Phrygia, was a prosperous city sitting on major road routes connecting the Aegean coast to the Anatolian interior. Its coins under Caracalla name a local magistrate — the archon Quadratus — whose tenure can only be approximately dated within the co-regency and sole reign period. Civic bronze of this type was struck for local exchange and religious festival use, never circulating far beyond the issuing city's own markets.

The ΕΠΙ ΚΟΔΡΑΤΟΥ formula places administrative responsibility squarely on the named official, a Greek civic tradition that doubled as a dating mechanism when consular years went unrecorded.
