1903 Louisiana Purchase Exposition Gold Dollar. McKinley Portrait. Proof-63 (PCGS). CAC.A beautiful and rare Proof striking of this popular classic commemorative type. Universally brilliant in finish, both sides also display full striking detail and handsome medium gold patina. The Mint produced 100 Proof Louisiana Purchase Exposition gold dollars each of the Jefferson and McKinley types. Delivered as they were before the circulation strikes, these specially prepared and distributed specimens are technically the first official gold commemorative coins produced by the United States Mint (discounting the 1848 CAL. quarter eagle, although a case can certainly be made for that issues commemorative status). These coins were originally issued in frames with certificates attesting to the fact that they were among the first 100 pieces struck from the dies. Obviously a rare coin given such a limited mintage, this lovely specimen is certain to see spirited bidding at auction.From the Collection of Samuel Morse Felton, 1926-2015.
