Great Britain
George VI bronze Proof Penny 1948 PR66 Red and Brown PCGS, KM845. Freeman-237 (R18). Remarkable in both appearance and technical quality, this proof specimen sets the portrait of George and the image of the seated Britannia ablaze in deep-purplish patina and luminous golden luster. Perhaps one of the finest mixtures of tone we've encountered on this type thus far, wholly satiating as such.
