Æ28 - Valerian and Gallienus ΑΙΛ ΕΡΜΕΙΑϹ ΠΡΥΤ ΚΥ/ΜΑΙΟΙϹ

Cyme was among the oldest Greek foundations on the Aeolian coast, and by the imperial period it had long since traded political relevance for the comfortable obscurity of a mid-tier Conventus city. The joint reign of Valerian and Gallienus — father and son ruling simultaneously — produced a brief window of co-emperorship that civic mints across Asia Minor exploited for local bronze issues, partly as expressions of loyalty during a period when the empire was fracturing under military pressure on multiple frontiers. Valerian's capture by the Sasanian king Shapur I at the Battle of Edessa in 260 AD abruptly ended the co-reign.

The prytanis named in the obverse legend, Aelius Hermeias, anchors this piece to a single magistracy term — the only administrative detail that distinguishes it from the dozens of otherwise anonymous Cymaean bronzes of the period.
