Æ29 - Gallienus (sole reign) (ΚΑΔΟΗΝωΝ, ΑΥΓΟΥϹΤΙΑ)

Cadi was a small Phrygian city granted the right to strike civic bronze under Roman oversight — a privilege that carried real political weight in a province where local coinage was a marker of municipal status. The joint ethnic legend pairing Cadi with Augustia reflects an administrative or honorific union between two communities, an arrangement documented at several Lydian and Phrygian mints but still not fully understood in its legal mechanics. Gallienus's sole reign, following his father Valerian's capture by Shapur I in 260, saw provincial civic minting across Asia Minor continue largely undisturbed even as the western empire fractured.
