These are believed to be restrikes made circa 1859 or later.
They exist in the following combinations:
Gold J141/P169 with about a dozen known.
Silver J142/P170 probably struck using a dime planchet as host. This is known only by a single example which appeared as part of lot 55 of the 1892 Woodside sale.
Copper J143/P171 with fewer than a half dozen known. Pollock lists only 2 or 3. An example was part of Woodside lot 55. These appear to be restrikes as they show die cracks on the reverse at 12:00, 5:00 and 9:00.
Nickel J144/P172 with only the example that was part of Woodside lot 55 believed to exist. Judd lists one as being ex Massachusetts Historical Society and Pollock lists one as ex Root, Appleoton, but no example was in the 12/1878 Cogan sale of Root's collection and the coin offered in Stacks 3/1973 sale of the MHS coins was misnumbered. That coin was either a J140/P167 or J140A/P168.
