George IV gold Proof Half Sovereign 1826, KM700, S-3804, PR63 Ultra Cameo NGC. As stunning as it is rare with abundant frost atop the central motifs and deeply mirrored, water-like reflectivity in the fields that confirms the designation. Tone is barely apparent around the peripheries. A coin that George IV himself would be proud to own! Krause catalog price(s) for this item: $200 in VF, $550 in EF, $950 in UNC.
Estimate: 4000-5000 USD
