Although described as regular dies trial pieces, these were actually deliberately struck for sale to collectors as part of complete off-metal sets. Examples were struck as follows: Copper J1176/P1318 with fewer than a half dozen known. Aluminum J1177/P1319 with only 2 or 3 known. Nickel J1178/P1320 with only the former Woodin-1914 ANS exhibit, Newcomer, Farouk, Pine Tree 9/74, Paramount 4/77 coin believed to exist. Photo courtesy of American Numismatic Rarities.
