This is muling of the Longacre obverse with the reverse for J235-J236/P282-P285 showing 'United States of America' on both sides. Longacre's French head design. Your editor, Saul Teichman, has always questioned whether this was designed by Longacre or Paquet as the 1859 half dollar patterns used Paquet's punches in the legend "United States of America". 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. They are known struck from 2 different reverse dies, one with Perfect Ribbon which are originals, and the other with Broken Ribbon. Those from the latter that show extensive die rust were struck circa 1869 or later. To view these reverse dies side by side, click here. Examples were struck as follows: Perfect Ribbon Silver J245/P301 with about a dozen known Copper J246/P302. Pollock left the number available but was unable to confirm its existence at the time he was writing his book. In fact, over a half dozen are known including one is in the Connecticut State Library ex Mitchelson, a second ex Heritage's 12/26/2000 online Internet sale and examples have since been offered in American Numismatic Rarities 1/2004 and Heritage 1/2004 sales. Broken Ribbon Silver J245/P303 with about a half dozen known. The Bass and Queller examples were struck from rusted dies and are obvious restrikes. Copper J246/P304 with about a half dozen known Note: The pedigrees in Pollock and other references should be taken with a grain of salt as it is often difficult to tell which reverse was employed from older catalog and online images. Incomplete obverse splashers in white metal JA1859-2/P3212 and JA1859-3/P3215 are also known. Image courtesy of Bowers and Merena.
