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 aluminum, only 2 or 3 are known.

These were also struck in copper J1434/P1577 with only 4 or 5 known.

Note: The die trials of this year are often found gilt due to the rarity of many of the gold denominations.
