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.
