Æ32 - Antoninus Pius L ΚΔ

Year 24 of Antoninus Pius's reign — rendered as L ΚΔ in the Alexandrian regnal dating system — places this issue in the final year before his death in March 161 AD. The Alexandria mint operated under a distinct civic coinage system, administratively separate from the imperial Roman mint, producing bronze for circulation exclusively within Egypt under the closed currency zone Rome enforced there. Coins struck outside Egypt could not legally enter; Egyptian issues could not legally leave. That policy kept Alexandrian bronzes in intensive local circulation, which explains the near-universal heavy wear on surviving specimens.
