Beautifully toned premium Gem quality for this scarce early Proof Liberty Seated half dollar issue. Iridescent cobalt blue, lilac-pink and golden-apricot patina is most vivid when observed with the aid of a strong light. Virtually full in strike with a lively finish to silky smooth surfaces. Only about 80 to 100 Proof 1858 half dollar are believed to exist today, nearly all of which are far below the present piece in terms of preservation. This is the jumping-off year for wide distribution of Proof coins to numismatists. Years ago the <em>Guide Book of United States Coins</em> used to commence Proof listings with this year and ignore earlier ones (except for half cents and silver dollars). If you are building a top-flight collection of Proof Liberty Seated half dollars from 1858 to 1891, this represents an important opportunity.,,PCGS# 6412. NGC ID: 27TH.,PCGS Population: 2; 1 finer in this category (Proof-67).,
