Although these are described as regular die trial pieces in the standard references, it is more likely that the off-metal 'trials' of this year were deliberately struck for sale to collectors in complete sets. Examples were also struck as follows: Copper J766/P851 with about a half dozen known. Aluminum J767/P852 with about a half dozen known. Nickel J768/P853 with only the former Woodin-1914 ANS exhibit, Newcomer, Farouk, 76 ANA example believed to exist. Photo courtesy of Stacks.
