The regular dies trial piece in white metal. The illustrated example was last offered as lot 939 in Lester Merkin's 10/72 sale where it was described as follows: "1855 Gold Dollar, Judd 175a. Regular dies, white metal, irregular flan, plain edge. Unc., gray tone with traces of original lustre better strike than many gold examples of this date. Unique, the discovery coin, formerly in the Breen collection and origin of the listing in Judd." Its complete pedigree is ex Farouk, Bolender 3/57, Breen, Merkin 10/72, Sloss. Its genuineness has been questioned along with a second example which is corroded. Both have the same gouge below the second S in States and a scratch above the second S in States. The Farouk sale also had another described as struck in brass. Photo courtesy of PCGS.
