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 as part of complete aluminum sets. Only 2 are known as follows: 1) Gschwend, Brand, Boosel-RARCOA 4/72, RARCOA 1/73, Stacks 1/87, Superior 10/90, Bowers and Merena 11/92, Bowers and Merena 1/97, ANR 7/05 - illustrated above and easily matched to the Gschwend sale plate.
