AR23 - Antoninus Pius L ΙΔ

Year 14 of Antoninus Pius's reign marked a period of unusual administrative stability in Roman Egypt — no military crisis, no succession anxiety, no currency reform. The Alexandria mint continued its distinctive billon tetradrachm production under tight imperial oversight, with the prefect of Egypt controlling output more directly than any other provincial mint in the empire. Milne's cataloguing of this type drew heavily on the Dattari collection, assembled by Giovanni Dattari in Cairo around the turn of the twentieth century and still the foundational reference for Alexandrian coinage of this period.
