George III bronzed Proof Penny 1797-SOHO PR64 Brown NGC, Soho mint, KM618, S-3777, Peck-1122 (VS). A seldom-offered copper, superbly detailed on the devices, with delicate blueish iridescence in the mildly reflective, rich brown fields. A couple light irregularities in the finish are of note, but the overall presentation remains rather pleasing.
