Great Britain
George VI Proof Crown 1937 PR67 PCGS, Royal mint, KM857. The strike is immaculate as is the centering and faint peripheral tones exist. Most notably though are the pristine fields which are flawless and harbor an effigy that is satin-like in color and nick free.
From the Cape Coral Collection of British Crowns
