1879 Liberty Head Double Eagle. FS-801. Doubled Die Reverse. AU-58 (PCGS). CAC.Appreciably semi-prooflike in finish, especially on the obverse, this lovely example is bathed in honey-rose patina that is a bit more vivid on the reverse. Near-fully defined with just the lightest friction precluding a Mint State grade. One of the most pronounced Doubled Die varieties in the Liberty Head twenty series, the 1879 FS-801 exhibits particularly pronounced doubling to the letters in the words E PLURIBUS, as well as the adjacent letters in the word TWENTY.From the Fairmont Collection.
