This is an incomplete obverse die trial, in copper, of Paquet's - not Longacre's - French head design from 1859 showing just the portrait. Kurt Brintzenhofe notes a July 1897 article in the American Journal of Numismatics on U.S. Assay Commission Medals by Edmund J. Cleveland also attributes the French head used on the 1860 to Paquet. It is unique and is ex New Netherlands 4/51 where described as a dime trial, 58 ANA where described as a half dime trial and, more recently in Heritage 1/07, Stacks 7/08 as PCGS64RB, Simpson-Heritage 1/21 - PCGS65RB. This piece is actually listed twice by Judd and Pollock as a half time trial in white metal P3203 in error. Photo courtesy of Heritage.
