Although described as regular dies trial pieces, these were more likely deliberately struck for sale to collectors as part of complete sets.
Examples were struck on follows:
Copper J1441/P1585 with about 4 or 5 known including the piece illustrated below.

Aluminum J1442/P1586 with about 2 or 3 known. Click on the thumbnail image for an enlargement.
Note: The die trials of this year are often found gilt due to the extreme rarity of many of the gold denominations.
