This uniface pattern trime shows just the reverse. It appears that 2 planchets were fed into the press at the same time as opposed to some kind of brockage or die cap error.
Does anyone have the piece showing just the obverse ?
It is believed to be unique and is ex H Chapman 6/1908 Taylor Windle sale lot 1308, Brand (journal #44209), Kelly 2/13/41 B.G. Johnson invoice, Bolt, Numismatics Ltd, Bowers and Merena 6/96, Fred Weinberg, Heritage 9/97, Heritage 11/03, Mike Byers, Heritage 5/07.
