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 J1340/P1484 with only 3 or 4 known. Aluminum J1341/P1485 with only 3 or 4 known. Photo courtesy of Bowers and Merena.
