Part XI. Non Errors:

First strike authentic;

Later strikes counterfeit

This 1985 cent shows a second strike that was delivered by a pair of counterfeit dies.  The counterfeit strike is vertically-oriented in the photos and appears on the left side of each face.  One of the counterfeit dies was tilted (vertically misaligned), which is why the strike is restricted to one half of the coin.  I have seen two similar specimens, both originating in Canada.
