Æ33 - Antoninus Pius L ΙΖ

Regnal year 17 of Antoninus Pius places this issue squarely within the most administratively stable decades of the entire Roman imperial period — a reign so uneventful by Roman standards that the Historia Augusta struggled to fill his biography. Alexandrian bronze production under Pius was prolific, the mint working through a long series of reverses tied to the Egyptian religious calendar and Nilotic iconography, making die matching against the Dattari and Emmett corpora the primary tool for precise attribution.

The L ΙΖ date formula — the Egyptian regnal year rendered in Greek — is the standard Alexandrian dating convention, running from the anniversary of accession rather than the Roman calendar year.
