Æ33 - Antoninus Pius L ΤΕΤΑΡΤΟΥ

This piece dates to Regnal Year 4 of Antoninus Pius — the Egyptian provincial dating system tied to the accession anniversary rather than the calendar year — placing the strike squarely in 140/141 AD, shortly after Antoninus secured his position following Hadrian's death in 138. The Alexandrian mint was among the most prolific provincial operations in the Roman world, operating under tight imperial oversight while retaining its own dating conventions and fabric distinct from Rome.

The L ΤΕΤΑΡΤΟΥ designation, Greek for "year four," is the mint's standard regnal notation. Antoninus Pius enjoyed one of the longest and most uninterrupted reigns of any emperor — 23 years — meaning fourth-year Alexandrian issues sit at the very opening of a reign that would see dozens of subsequent annual types from the same workshop.
