These are believed to have been struck originally by or for Joseph Mickley from dies sold by the Mint as scrap. The obverse is from Newcomb 2 dies and the reverse is from 1813 Sheldon 293 and were struck over several years, probably beginning in the early 1860s as a copper example was in W. E. Woodward's November 1862 sale of the Finotti collection.
About a dozen silver examples, such as the illustrated example above, were believed to have been struck by John Haseltine in the late 1870s. Both dies show extensive cracks and rust although the reverse die is not in the terminal die state known for the very last copper examples. For more on this, see Ira & Larry Goldberg's February 2009 Naftzger II sale where many in copper and one in silver are offered.
Additional information on these can be found in chapter 5 of Don Taxay's "Counterfeit, Mis-struck and Unofficial U.S. Coins" and also Mark Borckardt's article "Restriking the Issues: The Large Cent Restrikes of 1804, 1810, and 1823," Coinage of the Americas Conference, New York: American Numismatic Society, 1998."
Many examples are known in copper and were listed as J46A/P6220 in the 7th edition of Judd. As these are normally collected by large cent collectors and not pattern collectors, these copper examples were removed from the 8th and 9th editions.
