Æ23 - Gordian III & Abgar X Edessa

Osroene had been a client kingdom of Rome since Abgar VIII's submission in the late 2nd century, but by Gordian III's reign it existed in name only — the dynasty clung to legitimacy through Roman patronage while Shapur I's expanding Sasanian Empire pressed from the east. This coin is one of the last issued under Abgar X Phraates, whose reign ended when Gordian's successor Philip the Arab formally annexed Osroene and abolished the kingdom outright, ending over three centuries of Abgarid rule.

The joint portrait type — a Roman emperor paired with a local dynast on a provincial bronze — is rare in the Syrian frontier issues and reflects the peculiar semi-autonomous status Edessa still held in this period.
