Æ34 - Antoninus Pius L ΕΝΔΕΚΑ (ΟΥ)

Year 11 of Antoninus Pius's reign — rendered in Alexandria as L ΕΝΔΕΚΑ, the Greek numeral notation the Alexandrian mint used consistently across its regnal-year dating system. Alexandria operated under a distinct civic calendar that began on the first day of Thoth, meaning Alexandrian year 11 ran from late summer 147 into 148 by the Julian reckoning. This disconnect routinely trips up attribution on provincials where the Roman and Egyptian calendars overlap awkwardly across a single issue.
