Æ24 - Caracalla COL ALEXAN AVG

Alexandria Troas held the privileged status of a Roman colony — Colonia Alexandria Augusta — granted during the early imperial period, which gave it the right to strike its own bronze coinage using Roman colonial conventions rather than the Greek civic idiom common across Asia Minor. The city sat on a natural harbor and was seriously considered by Constantine as a site for his new capital before he settled on Byzantium.

The conventus of Adramyteum was an administrative judicial district, not a mint authority — the attribution places this coin geographically within Roman bureaucratic organization of the province of Asia.
