This is not in Pollock, Taxay and was missing in Judd prior to the 8th edition. I have assigned it number P3375 due to its closeness to JA1869-7/P3374 It is a complete obverse die trial in white metal of J748/P831. It is ex-Lohr, Empire Review 1/63, Bowers and Merena 6/96 lot 1207, Heritage 9/97 lot 6200, Stacks-Bowers 3/12. Photo courtesy of Stacks-Bowers.
