Æ28 - Commodus ΠΡΟΥϹΙΕΩΝ ΠΡΟϹ ΥΠΙΩ

Prusias ad Hypium occupied a geographically awkward position in Bithynia — situated inland along the Hypius river rather than on the profitable coastal routes — which made civic bronze coinage a pointed assertion of municipal ambition. Under Commodus, several Bithynian cities ramped up local bronze production, partly to fill gaps left by reduced central supply, partly to compete for honorific status within the province. The city's double ethnic formula in the legend, distinguishing the town from the river, appears consistently on issues of this period and reflects an ongoing civic identity project rather than any administrative change.
