Æ19 - Claudius ΑΥΤΟΚΡΑ, L ΙΒ

Year 12 of Claudius's reign — 51/52 AD — fell just two years before his death, almost certainly by poison, with Agrippina the Younger the primary suspect. Alexandria by this point was the largest mint producing bronze coinage in the Roman East, its output calibrated to local Egyptian reckoning rather than the imperial system, which is why regnal years appear on these coins at all. The L ΙΒ date formula is distinctly Alexandrian, borrowed from Ptolemaic administrative practice and never adopted elsewhere in the Roman provincial series.
