Elizabeth II Proof Penny 1963-(P) PR67+ Red PCGS, Perth mint, KM56. The only example thus far certified PR67+ by PCGS with a single PR68 graded finer. As one might expect, the surfaces appear pristine with a perfect strike and softly varied red color; certainly one of the finest extant. An example that is fully deserving of inclusion in an elite set.
