Proof S-Mint State Quarter
Obverse Die Cap
NGC PF 68 Ultra Cameo
This is the only known proof state quarter obverse die cap that has been discovered since the U.S. Mint began production in 1999. I originally purchased this at a Baltimore coin show in 2000 from a collector who had discovered it. I immediately sold it to a collector and thought I'd never see it again. Since then, NGC authenticated and certified it PF 68 Ultra Cameo.
It is a very deep obverse die cap and is in pristine condition. The state quarter design on the reverse has been obliterated due to striking many blank planchets since this die cap adhered to the obverse die. A spectacular and unique U.S. state quarter major mint error.
