Æ36 - Trajan L ΙΑ

Year eleven of Trajan's reign — rendered in Alexandria as L ΙΑ — places this issue squarely within the period of the First Dacian War's aftermath, when Egypt's grain revenues were being redirected to fund Trajan's extraordinary military buildups along the Danube frontier. The Alexandrian mint operated on a closed currency system: provincial bronzes like this could not legally circulate outside Egypt, and foreign coins entering the province were reminted, giving the Alexandria series an unusual continuity of local character.

The regnal year dating system used by Alexandria is itself a product of Ptolemaic administrative practice, retained under Roman rule as a concession to local bureaucratic tradition.
