Æ34 - Antoninus Pius L Ε

Year five of Antoninus Pius's reign — the regnal year marked by the L Ε (year 5) on this issue — coincided with a period of relative administrative stability in Egypt under the prefect Marcus Petronius Mamertinus. Alexandrian bronze coinage of this period was struck to a local standard entirely outside the imperial Roman denominational system, functioning as a closed currency that could not legally circulate beyond Egypt's borders.

The Emmett reference IV.4#546 places this among the diobol-sized issues of the sequence, though Alexandrian denomination assignments remain contested among specialists.
