Lot 33177. William IV gold Proof Sovereign 1831 PR64 Deep Cameo PCGS, KM717, S-3829B, W&R-261. Plain edge. A satisfactory and charming selection exhibiting a full cameo effect that yields a crisp contrast between William's bust and the mirrored fields surrounding. For their part the fields reveal only a few isolated wisps of handling and display a characteristic and intense reflectivity to several inches. Perennially popular as a type, and always in demand by collectors when encountered in better states of preservation. Ex. Eliasberg Collection (American Numismatic Rarities, April 2005, Lot 441); Belden Roach Collection (B. Max Mehl, February 1944, Lot 1380)
