Æ24 - Caracalla COL ALEXA(D) AVG

Alexandria Troas held the privileged status of a Roman colonia — formally Colonia Alexandria Augusta Troas — granted by Augustus, which gave it the right to issue bronze coinage in its own name rather than under the Greek civic tradition. That colonial autonomy is precisely why the reverse legend reads as an abbreviation of the colony's title rather than a standard Greek ethnic. Caracalla is known to have visited the city, and ancient sources including Dio suggest he developed an unusual attachment to the site, reportedly planning urban improvements there.
