PART VI. Striking Errors:

Silver Eagle Struck on Emery Disc

Definition: For a time the Mint produced a matte finish on silver eagle dies by applying a rough-surfaced emery disc to the die face and having the die strike a planchet.  The planchet was then supposed to be discarded and the emery disc peeled off the die face.  A few Silver Eagle coins have been found struck through the emery disc.  These either represent planchets that were not discarded or cases in which the emery disc was not peeled off the die face.  Coins struck through an emery disc show a very blurred, rough design.
