Great Britain
William IV pattern Proof Crown 1831, S-3833, ESC-273 (R4), L&S-3, KM715, plain-edged pattern having "W.WYON." on truncation in raised capital letters with serifs, medal-rotation die alignment ("medal die axis"), extremely rare, PR64 PCGS, a truly splendid proof in an old PCGS holder, nearly flawless, perhaps some almost invisible hairlines under the color (likely from being on velvet risers), full proof strike, reflective glassy surfaces, King William's bare cheek flawless, the marvelous crowned and draped royal shield on reverse simply perfect, rims untouched, and both sides are evenly and identically sheathed in a beautiful, delicate silvery gray and bluish gold iridescence. This is a fabulous example of this great rarity, the first version of the design used for making proofs for the Coronation sets. Most likely, engraver William Wyon was asked to remove his boldly placed signature, which he turned into a modest, incuse, simple "W.W." We cannot locate any recent sale of this great rarity. Linecar & Stone cite a listing in a 1964 Seaby catalogue for a then staggering £575. Priced in the 2013 SCBC at £20,000. The cataloguer, with some 40 years' experience handling British coins, cannot recall ever seeing this pattern before.From The Formosa Collection
