Æ24 - Caracalla COL ALEX AVG

Alexandria Troas, a Roman colony founded under Augustus on the site of ancient Antigonia, held exceptional strategic value as the primary embarkation point between Europe and Asia Minor. Its colonial status — and the right to strike autonomous bronze coinage that came with it — was periodically reaffirmed by emperors seeking regional goodwill. Caracalla's reign saw intensified activity at several Mysian colonial mints, likely connected to his movements through the eastern provinces during his ultimately fatal Parthian campaign.

The conventus of Adramyteum administered a coastline thick with rival civic mints, making Alexandria Troas's colonial issues politically distinct from the surrounding Greek imperial bronzes.
