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.

A single example is known struck in nickel J600/P666 with only the Farouk coin confirmed.
