Tetradrachm - Claudius II Alexandria

Claudius II died of plague in early 270 — one of the few third-century emperors to die in office from natural causes rather than assassination — and Alexandria continued striking in his name briefly after his death while news traveled slowly across the empire. The Alexandrian mint had by this point reduced its tetradrachms to a thin silver wash over a copper core, a debasement that accelerated sharply through the 260s as the Roman monetary system fractured under military pressure and supply shortages.

Milne 4265 falls in the final emission of his reign, making exact dating to life versus posthumous issue genuinely uncertain.
