Year 20 of Hadrian's reign — rendered as L Κ in Egyptian regnal notation — places this issue in the final stretch of his second and last visit to Egypt, which concluded around 130–131 AD. Alexandria's mint operated on an entirely separate reckoning from Rome, issuing coins by regnal year rather than consulship, a practice rooted in Ptolemaic tradition that the imperial administration never bothered to suppress. The resulting series gives modern scholars an unusually precise chronological tool for mapping Hadrian's policy shifts and his personal movements through the province.
