Æ37 - Valerian and Gallienus ΚΑΙϹΑΡΕΩΝ ΒΑΓΗΝΩΝ

Bagis was a minor Lydian city whose civic coinage output was modest at best, and issues naming both Valerian and Gallienus as co-emperors compress into a narrow seven-year window before Valerian's capture by Shapur I at the Battle of Edessa in 260 AD — the first and only time a reigning Roman emperor was taken prisoner by a foreign enemy. That catastrophe effectively ended the Valerian-Gallienus joint authority and terminated the provincial series that depended on it.

The city's Greek ethnicon ΒΑΓΗΝΩΝ is the primary means of attribution; Bagis produced no coins under sole Gallienic authority after 260.
