Great Britain
George IV gold 2 Pounds 1823 MS64 PCGS, Royal mint, KM690, S-3798. One-year type. Frosted in the centers with dazzling reflectivity in the fields and light tone around the edge. An amazing survivor of the type, and quite possibly the finest example we have seen. Only surpassed by a single "+" graded coin at PCGS.
Estimate: 4000-5000 USD
