Æ36 - Antoninus Pius L ΕΝΔΕΚΑΤΟΥ

Year 11 of Antoninus Pius's reign — the regnal year encoded in ΕΝΔΕΚΑΤΟΥ — places this issue precisely in 147/148 AD, the same year Antoninus held his third consulship and celebrated the 900th anniversary of Rome's founding. The Alexandrian mint ran a notably diverse series that year, producing more reverse types than in most adjacent regnal years, likely tied to the anniversary festivities rippling even into provincial coinage programs.

At 36mm, this is among the larger bronze denominations from the Alexandrian sequence, corresponding to the diobol range in some cataloguing traditions, though the denomination terminology for this series remains contested among specialists.
