This is one of the few branch mint die trials known.
Only 2 examples are known as follows:
1) Newcomer, Boyd, Farouk lot 1967, Merkin 9/67 sale lot 534, David Bullowa in 1972, G.H Wolfe, Heritage 2000 FUN sale where it sold for $16,100.
2) B/R RCR #44 & #46, B/R 4/83, Stacks 9/94, Simpson-Heritage 9/20 - PCGS65RB
A single specimen, struck in nickel - J1453B/P1602, is also known to exist. It is ex 1892 Woodside sale lot 318 with one of the above copper coins (probably the Farouk coin), Wayte Raymond's 2/42 sale as lot 16, B. Max Mehl's Olsen sale as lot 372A, New Netherlands, Kagins 6/67, Kagins 11/71 lot 1208, 1993 ANA sale as lot 8008 as a mint error, Superior 7/03 as NGCMS64, Simpson - PCGS64. It is very weakly struck apparently on a three cent nickel planchet and is shown below.
It appears likely that all three of these pieces were made at the Philadelphia mint as fantasy pieces for a collector's cabinet. It is interesting to note that the nickel and Stacks 9/94 copper specimens were described as business strikes whereas the upcoming Wolfe coin was graded as a proof in the Merkin sale.
There appear to be at least 4 silver examples which have been described and/or encapsulated as a branch mint proof.
1) Kagins 11/71 lot 1207, Stacks 9/83 lot 677, Jay Parrino 1999 Fixed Price list, Superior 3/00, Superior 1/08 as PCGS-SP65, B/M 8/09 as PCGS-SP66, Simpson collection-Legend 7/14 - PCGS-SP66+.
2) RARCOA-Auction 90 8/1990, Heritage 8/92 as ANACS-SP64, Heritage 1/96, StacksBowers 8/12 as NGC-SP65 now PCGS-SP66
3) Heritage 2/03, Simpson, Legend 7/14, Heritage 10/14, Heritage 1/15 FUN, Heritage 8/17 ANA - NGC-SP65
4) James A Stack-Stack's 1/90, graded as gem Unc but it was fully prooflike and brought a proof price.
The obverse die has filled 'A's in the lettering and the reverse has recut 'E's and these appear to have been struck in medal alignment.
