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.

Examples were struck as follows:

Copper J1371/P1516 with only 2 or 3 known.

Aluminum J1372/P1517 with only 2 or 3 known.
