Great Britain
George IV gold Sovereign 1821 MS64 NGC, Royal mint, KM682, S-3800. Approaching prooflike quality in the fields with eye-catching, vivid accents of orange tone over portions of both sides; a very scarce grade for this type. For the sake of accuracy, several deliberate, albeit barely visible marks, are mentioned in the field behind the horse's tail.
