Æ22 - Trebonianus Gallus COL AVG TROAD

Alexandria Troas, a Roman colony founded by Antigonus and refounded under Lysimachus before Augustus formalized its colonial status, maintained an unusually long run of autonomous bronze coinage compared to most Asian Greek cities of the third century. Trebonianus Gallus came to power after the death of Decius at Abrittus in June 251 — the first emperor killed in battle by a foreign enemy — and his two-year reign produced a relatively narrow window for provincial issues. The IX#422A reference places this among the less-documented die pairings from the Troad's final active minting phase.
