Æ34 - Antoninus Pius L Ε

Year five of Antoninus Pius's reign — the regnal year marked by the ΛΕ (year 35 of the Alexandrian era) — fell during a period of relative administrative stability in Egypt, when the prefect's office was managing grain logistics for Rome with unusual efficiency. Alexandrian bronzes of this size were the workhorses of local commerce, circulating in a monetized economy that ran on a closed currency system: Roman coinage was exchanged at the border and Egyptian tetradrachms and large bronzes kept internal.

The specific reference IV.4#405 places this within Dattari-Savio's exhaustive die study, where several obverse die links connect issues across regnal years four and five.
