This is a private striking, possibly by Joseph J. Mickley or Montroville Dickeson, from dies sold by the mint as scrap in the early 1860s. It first appeared in Woodward's Colburn sale according to Taxay.
The obverse is believed to be an altered 1807 die, redated to 1804. It shows several cracks, one of which bisects the obverse from 11:30 to 5:30. The reverse has not been identified. Both dies are heavily rusted.
Examples are known as follows:
Silver with reeded edge J29/P6075. The listing in Pollock is a typo. The Judd coin was the example described as having some reeding on the edge.
Silver with plain edge J30/P6080. It may be unique with the former Bass Foundation example listed by Pollock. This is also probably lot 1494 of Kagin's 11/64 sale.
Brand owned 2 of these, edge not mentioned and were entered as journal #24841 and 82893. Raymond 2/42 and 1958 ANA lot 1465 are additional listings where the edge is not defined.
Copper with reeded edge J31/P6085 with at least the Kagin 1/75 sale piece existing per Pollock.
Copper with plain edge J31A/P6090 with 3 known including the Byron Reed and 2 examples ex Southern collection, Simpson collection in NGC61BN and PCGS63BN. One of the last 2 is ex H. Chapman's 1909 Metzger sale, Brand (journal #47954).
The Chapman bros 7/1901 and Low's 272 sale lot 298 are additional listings without edge being specified.
