Æ33 - Antoninus Pius L ΤΕΤΑΡΤΟΥ

This piece dates to regnal year four of Antoninus Pius — rendered in the Alexandrian dating system as L ΤΕΤΑΡΤΟΥ — placing it in the second full year after Hadrian's death in 138 AD. Alexandria operated its own civic mint under Roman provincial authority, producing bronze coinage calibrated to local Egyptian needs rather than the imperial weight standard. The Alexandrian mint was among the most prolific provincial operations in the empire, yet year-specific survivorship varies considerably, and fourth-year issues of Pius are less frequently encountered than those from his middle regnal years.
