AR23 - Antoninus Pius L ΙΔ

Year 14 of Antoninus Pius's reign marked a moment of relative administrative stability in Roman Egypt, where the Alexandria mint operated under tight imperial oversight through the prefect's office. The billon tetradrachms of this period were produced to a debased silver standard that had been declining steadily since the Flavians — by the mid-second century the silver content was low enough that Alexandrian coinage was effectively a local fiduciary currency, legally inconvertible outside Egypt's borders.

Dattari 2956 is well-documented across multiple collections, placing this among the more traceable types in the Year 14 sequence.
