Æ25 - Gallienus sole reign) (C TR (AS?), C A / TR (on vexillum)

Alexandria Troas was a Roman colony — formally Colonia Alexandria Augusta Troas — whose civic bronze coinage persisted well into the third century precisely because the city retained colonial status and the right to mint. Under Gallienus's sole reign, after Valerian's capture by Shapur I at Edessa in 260, the eastern provinces were left to manage their own affairs with limited imperial oversight, and local civic issues like this one filled the gap left by disrupted central supply.

The abbreviated legends referencing the colony's consular or tribal designations are notoriously difficult to resolve, which explains the queried attribution in the type designation itself.
