This is an 1822 obverse die trial in copper struck outside the mint from dies sold as scrap probably by Joseph J. Mickley or Montroville Dickeson in the early 1860s. It does not appear to match any Overton variety.
About 6 are known including 2 in the ANS and another, the Parmelee, Byron Reed example is in the Durham Museum. The illustrated example ex Farouk, Judd, Witham-Auction 81, Logan-B/M 11/02, Mike Byers.
