Æ22 - Trebonianus Gallus COL AVG TROAD

Alexandria Troas held the status of a Roman colony — Colonia Augusta Troadensis — granted under Augustus, which gave it the rare right to strike its own bronze coinage long after most Greek city mints had gone silent. By the time Trebonianus Gallus took power following the death of Decius at the Battle of Abrittus in 251, the city's mint was one of a dwindling number in the region still operating with any regularity. His reign lasted barely two years before he was killed by his own troops, who then backed Aemilianus — leaving a narrow production window for all issues bearing his name.
