1875 Shield Nickel. Proof-67+ (NGC).This beautifully toned specimen exhibits a target-like distribution to reddish-orange, antique gold, powder blue and lilac-rose iridescence. Striking detail is razor sharp throughout the design, and the surface preservation is as superb as the eye appeal. This is the finest Proof 1875 Shield nickel known to PCGS and NGC in the non-Cameo category, and it is a coin that will have no difficulty finding its way into an advanced collection. Remarkable Superb Gem preservation from an estimated mintage of 1,000 to 1,250 coins (per Bowers, 2006).
