Æ35 - Antoninus Pius L ΙΖ

Year 17 of Antoninus Pius's reign, which is what the "L ΙΖ" dating formula records — the Egyptian regnal year running from the Roman emperor's accession, recalculated through the Alexandrian calendar. The provincial mint at Alexandria operated under entirely separate administrative control from the Roman imperial mints, producing its own bronze coinage calibrated to local Egyptian denominational traditions rather than the Roman aes system. Antoninus Pius's reign was notably peaceful, which made Egypt administratively stable and the Alexandrian mint unusually productive across his full twenty-three year rule.
