Æ27 - Valerian and Gallienus ΕΠΙ Α (Ρ) ΕΥΑΡΕϹΤΟΥ ΜΕΙΛΗϹΙΩΝ

Miletus had been minting civic bronze for centuries by the time this joint issue appeared under Valerian and Gallienus, but the pairing of father and son co-emperors on provincial coinage reflected a deliberate dynastic messaging campaign following Valerian's elevation in 253. The magistrate name preserved in the legend — Euarestos — is one of the few documentary traces of local administrative personnel from Miletus in this period, making provincial bronzes like this one inadvertent historical records of civic office.

Valerian's capture by Shapur I at the Battle of Edessa around 260 effectively ended the joint reign in practice, though Gallienus continued issuing coinage in both names for a time.
