Although described as regular dies trial pieces, this was more likely deliberately struck for sale to collectors as part of complete copper sets.

T. Harrison Garrett had one and a double set was apparently stolen from the Iowa State Historical Museum.

About a half dozen are known.

These were also struck in Brass J593/P657 with supposedly only 5 struck including the piece illustrated below. We believe that there may be a couple more than that in actuality.
