Æ31 - Gallienus sole reign) (ϹΥΝΝΑΔΕΩΝ ΚΕΛϹΟΥ Β / ΑΡΧ - ΕΠ

Synnada, a Phrygian city best known in antiquity for its quarries of *marmor Synnadicum* — the white-and-purple pavonazzetto marble prized by Roman emperors for palace floors and sarcophagi — struck civic bronze coinage under local magistrates well into the third century. The archon name preserved in this issue's legend, Kelsos, anchors it administratively to a city still functioning with considerable autonomy during Gallienus's sole reign, a period when the empire was simultaneously hemorrhaging territory to the Gallic Empire in the west and the Palmyrene breakaway in the east.

Civic bronze production in the Conventus of Synnada effectively ceased shortly after Gallienus, making late magistrate-named issues from this mint among the last artifacts of Greek-style civic coinage in the region.
