As - Nero

Nero's aes coinage underwent a deliberate reform around 64 AD, when he reduced the weight standard of the as and adjusted the orichalcum and bronze denominations across the board — a debasement driven by the fiscal strain of his building campaigns and, almost certainly, the catastrophic fire that destroyed much of Rome that same year. The reformed bronzes circulated heavily throughout the empire and survive today in a wide range of conditions precisely because they were the everyday money of Roman commerce for decades after his death.

Nero was damnatus memoriae following his suicide in 68 AD, yet systematic destruction of his coinage never materialized at scale.
