Æ32 - Hadrian L ΚΑ

Year 21 of Hadrian's reign corresponded to 136/137 AD, a period when the emperor was already gravely ill and consumed with the succession crisis following the death of his first chosen heir, Lucius Aelius Caesar, who would himself die on New Year's Day 138. Alexandrian bronze coinage of this regnal year is relatively scarce compared to earlier years of his reign, likely reflecting disruptions in the civic mint's output during a politically unsettled period.

The L ΚΑ date formula — the Egyptian regnal year rendered in Greek — is the primary chronological anchor for the entire Alexandrian series under the Principate.
