George IV Proof Shilling 1821 PR64 PCGS, Royal mint, KM679, S-3810. Beautiful blue iridescent toning coupled with faint russet hues along the periphery give this coin superb eye appeal. One of just eight graded specimens seen by PCGS, only three of which are higher grade. An all-around lovely piece.
