Newly discovered 1867-S Half Eagle also shatters previous auction record in $10.665 million U.S. coins event; 1934 $10,000 Federal Reserve Note Leads $8.7 million U.S. currency auction.
The 1856 Proof Three Cent Silver is a very desirable rarity in the series with a mintage of merely 60 coins. Rare from MS60 through MS64. MS65 is very rare with higher end gems being extreme rarities. Cameo pieces are extremely difficult to locate as only a handful exist. Look for attractive toners as there are many in this series.
Obverse Description
A six-pointed star with a harp in the center is surrounded by UNITED STATES OF AMERICA on the periphery and the date positioned at the bottom. For the type II issues (1854-58) there are two frame lines around the star.
Reverse Description
The roman numeral III is centered in the design ensconced in a large, bejeweled letter C surrounded by 13 stars on the periphery. An olive sprig is added above the roman numerals.
