Although described as regular dies trial pieces, these were deliberately struck for sales to collectors as part of complete off-metal sets. Examples were struck as follows: Copper J1363/P1508 with at least 4 known including an example in the Connecticut State Library and the illustrated example formerly from the Hughes 7/80 sale. One ex Peters 1/75 is in a Wyoming collection. Aluminum J1364/P1509 with only 2 confirmed. Photo courtesy of American Numismatic Rarities.
