Æ30 - Gordian III ΕΦΕϹΙΩΝ (ΚΑΙ) ΑΛΕΞΑΝΔΡΕΩΝ ΟΜΟΝΟΙΑ

Homonoia coinage — issues celebrating concord between two cities — was a diplomatic currency in the most literal sense, struck to formalize or advertise political alignment between urban centers competing fiercely for Roman imperial favor. The pairing of Ephesus and Alexandria is notable: these were the first and second cities of the eastern empire by most reckonings, rivals in commerce, cult, and prestige, and their periodic homonoia issues reflect calculated alliance rather than any organic fraternity.

Under Gordian III, such civic coinage proliferated across Asia Minor as cities jockeyed for neokoros status and imperial attention during a reign managed largely by the praetorian prefect Timesitheus.
