Æ33 - Antoninus Pius L Ε

Year five of Antoninus Pius's reign — rendered here as L Ε — places this issue squarely in the early period of his administration, before the Alexandrian mint had fully settled into the rhythms of his long, uneventful principate. The regnal year dating system used at Alexandria is itself a product of Rome's accommodation of Egyptian administrative tradition, retained as a practical concession to a province that had kept its own calendar since the Ptolemies.

The Emmett reference IV.4#426 places this among a well-documented but numerically dense series; distinguishing individual types within Antoninus's fifth-year coinage requires close attention to reverse type rather than any feature the flan itself advertises.
