George IV Proof 1/2 Crown 1821 PR64 PCGS, Royal mint, KM676, S-3807. Beautiful steel blue and lavender toning cover this coin, giving it exceptional eye appeal. Though there are (a few) coins that are technically higher grade than this, it is hard to imagine one with more desirable toning. A great piece for the collector who prizes eye appeal above all else.
Estimate: 3000-4000 USD
