Æ23 - Hadrian L ΙΗ

Year 18 of Hadrian's reign — rendered as L ΙΗ in the Alexandrian regnal dating system — fell during his second extended visit to Egypt, which began in 130 AD and included the infamous drowning of his companion Antinous in the Nile. The Alexandria mint, operating under Roman authority but retaining its own dating conventions and Greek-language output, ramped up production across multiple types during these years, likely in direct response to Hadrian's physical presence in the province.

Bronze fractions from this mint circulate frequently in worn grades; the alloy composition and flan preparation varied enough that weight discrepancies within a single type are unremarkable.
