Great Britain
George III brown-gilt Proof Pattern 1/2 Penny 1788 PR63 Cameo NGC, Soho mint, KM-PnA63, Peck-966. A very scarce pattern with an intriguing gilding process that leaves the surfaces somewhere between a soft gold and bright bronze in hue, some handling wisps on the reverse discernable, but not overtly distracting.
