PART VI. Striking Errors:
Struck Through Miscellaneous Foreign Matter:
Struck through an Emery Disc
Definition: During the striking process, a foreign object enters the striking chamber and is struck along with the planchet. If the foreign object is thin, the design will still transfer from the die to the planchet. However, there will be some distortion of the design elements varying on the thickness of the foreign object that is between the planchet and the striking die.
