This is believed to be a striking from two Paquet reverses, one of which appears to have been ground down. Early editions of Judd book incorrectly list this as a die trial.
Analysis of the Queller coin by Dennis Terrant and Heritage has proven that the ground down reverse was, in fact, the Broken Ribbon variety as shown by the comparison images below courtesy of Dennis Tarrant and Brandon Gabrick.
At least 2 examples are known. The Pollock pedigrees are incorrect.
1) Farouk, Bolender, Hydeman, Bowers and Merena 9/88, Queller-Heritage 1/09 as NGC63BN, Simpson collection - PCGS63BN, illustrated above.
2) Cox-Stacks 4/62. This is now in the Smithsonian.
The Lohr collection piece could be either of the 2 listed.
Earlier listings for these include Fewsmith (1870), Lefferts (1881), Metzger (H. Chapman 2/1909) to Brand (journal #47955), Woodin-1914 ANS exhibit and Elder's 4/27/17 sale lot 401. From this last listing, it appears that a third specimen exists.
