Re:

Something I should have mentioned back when we were talking about the Lincoln cents, there was a case of an on purpose situation in the manufacturing of proof cents in 1979. They had an employee that was highly upset at the San Francisco mint where the proof sets were being made. He knew he was going to be fired and he had a bad attitude about his impending dismissal. In the production of the proof planchets, they are polished several different times to an extremely high polished look.

This was about September of 1979, just about the time the Type 2 mint mark was coming along. In an act of defiance, he went through and 'thumbed' hundreds, if not thousands, of planchets that became Type 2 Lincoln cents. If you look at enough 1979 proof sets, you will see an occasional thumb print on the cent, courtesty of an irate employee.

I know some errors were accidental, but it seems that some errors were 'accidentally on purpose!' It almost gives one the impression ( no pun intended ) that someone was doing something underhanded! I'd love to come across some of those quarters . . .
