Æ21 - Severus Alexander COL A (or AVG) TRO (D)

Alexandria Troas was a Roman colony — Colonia Alexandria Augusta Troas — whose coins were struck not by imperial authority but by the city itself, exercising the colonial privilege of local bronze production. Under Severus Alexander the city minted prolifically, and the COL A TRO abbreviation placing colonial status first was a point of civic pride in a region that had competed hard for that designation since Augustus refounded the settlement.

The Conventus of Adramyteum grouped cities across the Troad for administrative and judicial purposes. This particular reference, VI#4043, falls within a well-documented but often poorly preserved series; the small module and thin flans make complete legends rare.
