Although described as a regular dies trial piece in the literature, it is more likely that this was deliberately struck for sale to collectors as part of complete off-metal sets.

Examples were struck as follows:

Copper J787. This is unlisted in Pollock. If any do exist, they are probably masquerading as a regular issue proof.

Aluminum J788/P875 with only 2 or 3 believed to exist.

Nickel J789/P876 and is believed to unique.
