This pair of dies was never intended for regular coinage, but was made to test the concept. Used to strike gold impressions of a diameter larger than currently in use, perforated so that the value of gold could be maintained in a larger-format coin. Two examples of J-137 are known, one using an already struck 1846 quarter eagle as the planchet, and the other an 1859 quarter eagle as the planchet. All varieties are restrikes, including gold impressions.
