1876 Nickel Three-Cent Piece. Proof-66+ Deep Cameo (PCGS). CAC.;A lovely Gem that ranks high in the Condition Census for this Centennial year Proof issue. Brilliant and free of even trivial blemishes, both sides allow full appreciation of a sharply cameoed finish. From an unknown mintage that is often estimated at 1,150+ pieces, but which is probably on the order of 1,500 to 2,000 coins. This is one of the best produced, most carefully preserved examples that we have ever had the privilege of bringing to auction.
