1879 Trade Dollar. Proof-65 (PCGS). CAC. Light golden rose surfaces allow ready appreciation of a finish that flirts ever so close to a cameo designation. The strike also imparted razor sharp definition throughout the design, both sides carefully preserved to readily uphold the validity of the Gem rating from PCGS. The 1879 is first of the Proof-only dates from the end of the Trade dollar series, the mintage 1,541 Proofs.
