The following appears to be an obverse die trial of the 1910 Lincoln cent. It is struck on an oversized irregular copper planchet that is the weight of a standard cent. It is unknown if this is a deliberate die trial or some sort of die cap mint error. It has been graded as AU58 by PCGS as a die trial and not a mint error. We are calling it JA1910-1/P3528 for now although, its status, as mentioned above, continues to be questioned. It was not placed in the new Judd book due to the lack of concensus regarding its status. Photo courtesy of Mike Byers.
