Æ33 - Antoninus Pius L ΙΘ

Year 19 of Antoninus Pius's reign, rendered in Egyptian reckoning as L ΙΘ, places this bronze squarely within the most administratively stable decade the province had seen in generations. Alexandria's mint operated under strict prefectural oversight, and the regnal year dating system used exclusively in Egypt meant these coins never circulated beyond the province — a deliberate monetary boundary Rome maintained to keep Egyptian grain revenues insulated from the broader imperial economy.

Dattari-Savio IV.4 #1788 is a well-documented type within a prolific reign, but Alexandrian bronzes of this module frequently show uneven flan preparation, a persistent characteristic of the local workshop rather than any specific die failure.
