1856 Liberty Seated Half Dollar. Proof-63 (PCGS).;Delicate golden-gray iridescence greets the viewer from both sides of this uniformly reflective specimen. Boldly to sharply struck in most areas with minimally marked Choice surfaces. Struck prior to the Mints efforts to market Proof coinage to a wider audience among contemporary Americans, the 1856 half dollar has an unknown mintage that Q. David Bowers (<em>A Guide Book of Liberty Seated Silver Coins</em>, 2016) estimates at just 20 to 30 pieces. This rare survivor is sure to see spirited bidding among advanced numismatists.;
