Æ13 - Antoninus Pius L ΚΔ

Year 24 of Antoninus Pius corresponds to 160–161 AD, the final regnal year before his death in March 161. Coins struck in Alexandria during this period carry the LΚΔ date marker — the Egyptian dating system that makes Alexandrian bronzes among the most precisely datable provincial issues in the Roman world. At under 2 grams, this piece sits at the lower edge of what the Alexandrian mint regularly produced, likely a subsidiary denomination circulating alongside the billon tetradrachm that dominated Egyptian commerce.
