Although described as regular dies trial pieces, these were deliberately struck for sale to collectors as part of complete off-metal sets.
Examples were struck as follows:
Copper J1179. This is unlisted in Pollock. If any do exist, they are probably masquerading as a regular issue proof.
Copper-Nickel J1180/P1321 with only 2 or 3 believed to exist. It is highly possible that these are some sort of mint error.
Aluminum J1181/P1322 with only 2 or 3 known including the illustrated example from an October 1940 Bluestone sale and the Loye Lauder piece.
There is also a listing for this piece in nickel J1182/P1323. We believe this piece to be a mint error struck either on a planchet intended for a foreign coin or on a nickel 3 cent planchet. For more on this, click here.
