Æ29 - Valerian and Gallienus ΕΠΙ ΑΡΧ ΙΟΥΛ ϹΑΤΟΡΝΕΙΝ/ΟΥ ΠΡΙΗΝΕΩΝ

Priene issued this bronze under the joint reign of Valerian I and his son Gallienus, a co-emperorship that began in 253 when Valerian was elevated by his troops following the death of Aemilianus. The archon named in the legend — Julius Satorninos — was a local magistrate whose tenure anchored the coin's dating, a common practice in Ionian civic issues where municipal officials effectively signed the coinage.

Priene was a declining city by this period, its harbor long silted over by the Maeander river, stripping it of the commercial relevance it held in the Hellenistic age. Civic bronze production here ends abruptly with the 260s, when the broader collapse of provincial Greek coinage terminated most Asian mint activity.
