Æ33 - Antoninus Pius L ΙΖ

Year 17 of Antoninus Pius's reign corresponds to 153–154 AD, a period of pronounced administrative stability in Egypt — the province had been under direct imperial control since Augustus and the Alexandrian mint operated almost as a closed monetary system, producing bronze coinage that rarely traveled beyond Egypt's borders. The L ΙΖ dating formula, marking regnal year 17 in Greek, was standard practice for the Alexandrian mint and allows precise attribution impossible for most provincial issues.

At 33mm this is among the larger module bronzes the mint produced under Pius, likely circulating at the diobol or tridrachm level within Egypt's idiosyncratic denomination structure.
