Great Britain
George VI Proof Crown 1937 PR65 Cameo PCGS, Royal mint, KM857, S-4079. Tone free and displaying thick frost over George's portrait that results in deep cameo contrast, with more delicate frost on the reverse. Due to the refined appearance, especially on the obverse, possibly a 'VIP' striking of the issue, but difficult to determine definitively. A single instance of contact below George's nose prevents a finer technical designation.
