The Blakesley Effect is a term used to describe inefficient metal flow, opposite a clip on a coin ( "opposite a clip on a coin" it means the effect will be more or less CW/CCW180 degrees around the rim) from the clipped area., when the rim is formed and the subsequent imperfect or incomplete rim formed at that position after striking.

To tell whether or not your coin exhibits the Blakesley effect, simply check the rim of the coin directly opposite the clip. If it appears the details are lacking in that area and the rim appears flat, then it is more than likely that you have a genuine clipped planchet error.

Clipped planchets occur when a thin strip of coining metal is fed into a machine for blanks to be punched out. Sometimes the strip of metal will not be properly fed into the punch, which causes a blank to be punched out that overlaps the spot where an earlier blank was punched out.
