Netherlands
Willem I Proof 5 Cents 1819 PR64 Cameo NGC, Utrecht mint, Torch and Caduceus privy marks, KM52, Schulman-315 (RR). A spectacular early Proof of the Kingdom of the Netherlands, fully brilliant with tiny patches of surface patination and appealing cameo contrast. Faint die cracks and some die polish become visible with the aid of a glass, but are not distracting and have negligible effect on the reflectivity of the fields.
