1873 Trade Dollar. Proof-63 Cameo (PCGS).This lovely specimen combines an obverse ringed in reddish-gold peripheral toning with a reverse dressed in even apricot-gray patina. Both sides readily reveal bold cameo contrast between fully struck devices and mirrored fields as the surfaces rotate under a light. The 1873 is the premier Proof in the trade dollar series, the mintage 865 pieces. Survivors are rarer than those of the more highly regarded Proof-only issues of 1878 to 1883, especially in Choice and higher grades, as here. A find for the first year Proof type collector or advanced trade dollar enthusiast.PCGS Population: 17; 18 finer in this category (Proof-65 Cameo finest).From the Marc D. Cohen Collection.
