Æ28 - Valerian and Gallienus ΕΠ ΓΡ ΤΙΒ ΚΛ ΑΡΤΕΜΑ ΤΡΑΛΛΙΑΝΩΝ

Tralles, a prosperous city in Lydia, held the rare distinction of issuing coinage under joint imperial authority during the co-reign of Valerian and his son Gallienus — a period defined by extraordinary military pressure on Rome's eastern frontier, including Valerian's catastrophic capture by the Sasanian king Shapur I at the Battle of Edessa in 260 AD. The magistrate named in the legend, Tiberius Claudius Artemas, was a local official whose name appears on a small cluster of issues, tying this coin to a specific administrative moment in the city's civic minting history.
