Great Britain
George V gold Proof Sovereign 1911 PR66 Cameo NGC, KM820, S-3996. Almost at the peak of quality for the type, with only two examples graded higher (both PR67s) in NGC's database. Essentially flawless; the fields flashy and reflective yet textured with numerous die-polish lines, the devices richly frosted and immaculately rendered. For the high-tier collector of British Sovereigns, it would be near-impossible to upgrade upon this premium gem Proof.
