George III Proof Shilling 1820 PR65 NGC, KM666, S-3790. Reeded edge. Of extreme rarity. A lovely example with reflective surfaces, richly toned in shades of deep grayish mauve with blue and amber-gold iridescence. Clearly produced to an exceptionally high standard, a sublime proof representative of George III's final Shilling issue.
