William IV Proof Shilling 1834 PR64 NGC, Royal mint, KM713, S-3835. Very rare; one of only four graded (three by NGC and one by PCGS) and tied with two others for the finest certified. Dark steel gray toning with light russet iridescence in the fields. There have been no other examples of this type on the open market in at least the last decade, and as such it is very difficult to provide an accurate estimate.From The Law Collection
