1880 Trade Dollar. Proof-65+ Cameo (NGC).，This pretty example exhibits mottled steel-blue and reddish-copper peripheral patina around an otherwise untoned obverse. The reverse, equally attractive, is dressed in even golden-apricot iridescence with subtle powder blue highlights here and there at the borders. The devices are primarily full in strike with a soft satin texture that contrasts nicely with mirrored reflectivity in the fields. Smooth and inviting, this gorgeous Gem is sure to see spirited bidding at auction.<p>1880 is the third year in which the Philadelphia Mint struck the trade dollar solely in Proof format, and the second in which it was the only coinage facility to produce examples of this denomination. Survivors from a mintage of 1,987 pieces are always in demand, not only for inclusion in trade dollar date sets, but also as Proof type candidates. This is an exceptionally well produced and preserved specimen that will please even the most discerning numismatist.，，
