Lincoln Memorial Penny Struck Through Capped Die Error - Penny Error Brockage Struck Ghost Image of Lincoln

This listing is for the Lincoln Memorial Penny Struck Through Capped Die Error.  A coin struck through a late-stage die cap will show a strong “ghost image” of the raised design. Most such errors involve die caps affixed to the hammer die. A hammer die cap begins when a coin sticks to the hammer die.  That coin proceeds to strike a succession of planchets. As it does so, the coin expands, and its margins grow upward to surround the die neck.  This phenomenon is called “cupping”.   Eventually, the die cap assumes a thimble shape.  Any design originally present on the working face of the die cap grows progressively fainter and more distorted.  Eventually, no design is left, and all you have is a thin cap bottom that has molded itself to the recesses of the die face. Great Find!!
