Æ25 - Trajan ΙΕΡΑΠΟΛΕΙΤΩΝ

Hierapolis in Phrygia sat atop one of the ancient world's most lucrative thermal spring systems, and the city's civic coinage under Trajan reflects a municipality flush with revenue from its textile industry — particularly wool dyeing, which the mineral-rich waters made exceptionally productive. The city held assizes as part of the Cibyra conventus, one of the administrative districts through which Roman governors dispensed justice across Asia Minor, and local bronze issues like this one circulated primarily within that regional economy rather than beyond it.

The conventus system gave cities like Hierapolis periodic influxes of visitors and commercial activity during court sessions, sustaining demand for low-denomination civic bronze.
