AR24 - Nero ΠΡΟΝ ΝΕΟΥ ΣΕΒΑΣΤΟΥ, L Ϛ

Year 6 of Nero's reign in Egypt, this tetradrachm falls squarely within the period when the Alexandria mint was systematically debasing its silver — a process Nero accelerated empire-wide around 64 AD but which Egypt's closed currency system had already been managing independently for decades. The billon content here is notably better than what the same mint would produce by the end of his reign, making early-regnal examples a useful marker for tracking the debasement curve.
