GREAT BRITAIN. Sovereign, 1831. London Mint. William IV. NGC PROOF-64 Ultra Cameo.S-3829B; Fr-383; KM-717. Plain edge variety. Presenting astounding cameo depth with stark frost appearing atop the motifs and impressive reflective depth existing in the fields. An unquestionable top tier survivor from this elusive proof issue with the added nuance of having been struck from obviously rotated dies (around 40 degrees!), an attribute that is rarely observed on these mindfully-produced proof issues.
