Æ15 - Trajan ΑΒΥ

Abydus, positioned at the narrowest point of the Hellespont, had been strategically critical since antiquity — Xerxes built his famous pontoon bridges there in 480 BC, and the city retained enough local prestige under Roman administration to continue issuing its own civic bronze well into the imperial period. The magistrate abbreviation ΑΒΥ identifies the issuing authority as the city itself rather than a named official, a convention common to smaller Asian conventus mints under Trajan.
