Great Britain
George VI gold Proof 5 Pounds 1937, KM861, S-4074, PR65 NGC. A coveted issue at the Gem level with motifs and fields that are typically contrasted for the date and surfaces that maintain even, tone-free coloration. A single mark behind George's head is noted as the likely reason that an even higher grade wasn't awarded.
