Æ33 - Hadrian L ΚΑ

Year 21 of Hadrian's reign — Regnal Year ΚΑ — fell during the emperor's final extended stay in Egypt, a province administered under a monetary system deliberately isolated from the rest of the empire. Alexandria ran its own closed currency: Roman coins did not circulate freely there, and Alexandrian bronzes did not travel far beyond the Nile delta. The tetradrachm dominated, but these large bronzes filled the gap for everyday exchange within the city itself.

Hadrian visited Egypt in 130–131 AD, during which his favourite Antinous drowned in the Nile. The coins struck in the years immediately following that visit carry unusual iconographic variety, likely reflecting sustained imperial attention to the Alexandria mint.
