Æ19 - Hadrian L ΔΕ

Year 10 of Hadrian's reign corresponds to his celebrated tour of Egypt in 130 AD — but this piece predates that visit by several years, struck during a period when Alexandrian civic bronze was being produced in remarkable volume to service the monetized Egyptian economy. The Alexandrian mint ran a distinct regnal year dating system, with "L ΔΕ" marking regnal year 10, a convention inherited from Ptolemaic practice and maintained stubbornly through the Roman imperial period.

Alexandria remained the only mint in Egypt authorized to strike bronze for local circulation.
