Great Britain
George III Proof Shilling 1817 PR64 PCGS, Royal mint, KM666, S-3790. Plain edge variety. Deeply toned, this lovely piece exhibits flashy surfaces underlying the dark iridescent hues. The reds and greens darken further to a stormy gray along the edges of the sharp devices while betraying very little evidence of post-strike handling.
