1903 Louisiana Purchase Exposition Gold Dollar. McKinley Portrait. Proof-64 (PCGS).A lovely and scarce Choice Proof striking of this classic commemorative gold issue. Fully impressed with razor sharp definition, the devices also exhibit a soft satin texture that contrasts minimally with a reflective finish in the fields. The entire package is dressed in vivid deep gold patina, both sides also revealing subtle pale silver overtones as the coin rotates under a light. A lone carbon spot at the obverse border over the letter M in AMERICA will serve a as useful identifier to track this specimen through future market appearances.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 issued in frames with certificates attesting to the fact that they were among the first 100 pieces struck from the dies (bidders are encouraged to see the following lot in this sale for an opportunity to acquire the frame and certificate that were consigned alongside this Proof). Obviously an elusive coin given the limited mintage, this impressive specimen would serve as a highlight in an advanced cabinet.
