Although these have been described as regular die trial pieces, this is believed to have been deliberately struck as part of a unique copper set from the quarter to the double eagle, including the rare 1884 trade dollar, given to A.M. Smith, who authored the Mints visitor's guides. Its full pedigree is A.M. Smith-Bolender 2/36 lot 34, Bolt-Stacks 4/66, Kagin 1/75, Superior 10/89, Simpson-Heritage 1/24 FUN - PCGS63, gilt. Regrettably, it has been gilted masking the peculiar discoloration on the neck which is visible on the gold proofs. Photo courtesy of PCGS.
