Error metal flaw lamination. You can still see some of the design strike with a sliver of metal missing.
Partial delamination story. Mint trying to keep a portion of Silver off of millions of coins w/ a new machine designed to strip of said weight per each coin causing a lamination error.
Fascinating story portion::
☆ ☆Elsewhere in the testimony it is revealed that the separation was accomplished using a “delamination inspection machine” built by American Machine & Foundry. Thirteen prototypes of this machine. layers split off, or de-laminate, prior to being struck. It was expected to ultimately test up to 50 planchets per second, and the best way I can think of it doing that would be by weight. one-sixth of the thickness of a planchet, and so a de-laminated planchet would be 16.67% underweight. When sorting silver coins, just set your desired weight of the silver coins less 7% weight lighter when delaminated
Great find. Scarce error. *Should be graded & certified.
