Æ33 - Antoninus Pius L Κ

Regnal year 20 of Antoninus Pius, placing this squarely in one of the most administratively stable decades the Roman Empire ever produced — which is precisely why Alexandrian bronze from this period is so often overlooked. The Alexandria mint under the Antonines operated as a closed currency system; provincials could not legally use Roman imperial coinage, forcing all Egyptian commerce through locally struck pieces like this one.

The mint's output in year 20 was substantial, and survival rates reflect it.
