William IV gold Proof 1/2 Sovereign 1831 PR66★ Ultra Cameo NGC, KM716, S-3830, W&R-267 (R3). Small sized planchet. The best example of this type we have had the pleasure to offer, with a single PR66+ specimen its technical superior in NGC's database (yet lacking the 'star' designation implying an inferior visual appeal) and nothing comparable graded by PCGS. Interestingly, despite the high production standard for this Proof offering, its legends show faint traces of being double-struck, adding a slight numismatic intrigue to what is already an enticing selection. Perfectly finished with mirror fields and matte frosted devices, practically unmatchable for quality and certainly for aesthetic effect.
