Although described as regular dies trial pieces, these were actually deliberately struck for sale to collectors as part of complete off-metal sets.
The aluminum and steel trials for this year used the same overpolished reverse die as used on the 1865 pattern J418/P490. The copper ones apparetnly did not as the example in Heritage 4/14 sale was not from this reverse.
Examples were struck as follows:
Copper J687/P768 with fewer than a half dozen known.
Aluminum J688/P769 with only 3 or 4 known.
Steel, pure nickel or iron J689/P770 with only one known. It is ex Brenner-1914 ANS exhibit, Lohr, Bowers and Ruddy 1975 inventory, B/M 9/2001, Wilcox - PCGS61.
We would like to see this and its companion pieces J808/P896 and J1058/P1193 analyzed.
