Æ34 - Antoninus Pius L ΙΖ

Year 17 of Antoninus Pius corresponds to 153–154 AD, a period of administrative calm in Egypt that makes the coin historically unremarkable by imperial standards — but that very stability is why Alexandrian bronze production was so consistent and well-organized under his reign. The Alexandrian mint operated on a regnal year system unique among Roman provincial mints, stamping LΙΖ (year 17) to distinguish annual output in a way Rome itself never did for aes coinage.

At 34mm this falls among the larger Alexandrian denominations, sometimes catalogued loosely as drachms, though the precise denominational structure of Roman Egyptian bronze remains disputed among specialists.
