Æ22 - Trebonianus Gallus COL AVG, TROA

Alexandria Troas retained the right to strike autonomous bronze coinage well into the third century, an unusual privilege tied to its status as a Roman colony — Colonia Alexandria Augusta Troas — granted under Augustus. The city's mint was notably productive under Trebonianus Gallus, whose two-year reign followed the chaos of Decius's death fighting the Goths at Abritus in 251. Provincial issues from this mint are frequently assigned to the Conventus of Adramyteum for administrative purposes, though the coins themselves circulated locally around the Troad.
