Æ19 - Gordian III ΑΒΓΑΡΟϹ ΒΑϹΙΛΕΥϹ

Edessa occupied a uniquely awkward position in the third century — a nominally autonomous client kingdom under Roman suzerainty, ruled by the Abgarid dynasty while Parthian, then Sasanian, pressure mounted from the east. This coin is a product of that tension: a local civic issue bearing the name of king Abgar, struck concurrently with the Gordian III imperial series, signaling loyalty to Rome while asserting dynastic identity. The Abgarids had converted to Christianity — possibly the first ruling house to do so — making Edessa an anomaly in every direction.

The SNG Copenhagen 215 variant distinction is worth noting for attribution purposes.
