Described as regular dies trial pieces, we believe the pieces whose pedigrees are listed below are actually mint errors.
Examples were struck as follows:
Copper J400/P468. We have not been able to confirm the existence of any example.
Copper-Nickel J401/P469 with only 2 or 3 believed to exist including:
1) Parmelee, Byron Reed, Durham Museum, illustrated above
2) Champa-B/R 5/72.
Both are on 47 grain planchets and the Byron Reed example has been described as having "flat spot on edge at 11:00 and missing reeding 7:30 - 11:00" as illustrated.
Nickel J402/P470. Only the Woodin-1914 ANS exhibit, Farouk example is confirmed and it was described as "nickel, small flan" in that sale. It was probably the piece earlier sold as lot 2064 of Cogan's 10/1865 F.S. Edwards sale.
Woodside lot 148 was described as copper-nickel on a small planchet and is either the Champa coin or part of the pedigree of the nickel piece above.
