George IV Proof 1/2 Crown 1826 PR63 Cameo PCGS, Royal mint, KM695, S-3809. Light gray toning in the central devices, gradually spreading out to darker hues along the edges with some deep blue iridescence right along the periphery give this coin a charming look. Some light hairlines in the fields, which are mostly obscured by the lovely toning.
