Great Britain
George VI gold Proof £5 1937, S-4074, KM861, PR65 Ultra Cameo NGC, a gorgeous coin having deeply mirrored fields and distinct cameo or frosted contrast between the king's bust and the surrounding open field, and the same effect on the reverse with Saint George. One short pin-scratch on the reverse field at about 2 o'clock keeps this beauty from an even higher numerical grade.
