Jim0815 Pillar of the Community United States 5240 Posts	Posted 05/02/2018 4:33 pm I found this 1991 P LMC with what appears to be three rims. I have seen many doubled rim cents but haven't ever come across one with three. I know it was struck ever so slightly off center. How did this happen? Report this Post to the Staff

Crazyb0 Rest in Peace 10197 Posts	Posted 05/02/2018 5:55 pm Overpressure strike, that's call "rim finning". The strike forced too much metal to compress(note rear) causing the excess to squirt upwards along the collar. Report this Post to the Staff

Not the opposite side of the rim is not affected. http://www.error-ref.com/?s=finning Report this Post to the Staff
Conder101 Bedrock of the Community United States 17884 Posts	Posted 05/03/2018 10:42 am I don't think it is the fin that he is talking about. I think he is referring to the doubling of the INNER edge of the rim. Report this Post to the Staff

coop Bedrock of the Community United States 62064 Posts	Posted 05/03/2018 8:58 pm Note the fattening line? That area is where the fin took a hit and fin was bent over. That is why it looks like three rims. It is an illusion of the bent over rim area. Edited by coop 05/04/2018 12:19 am Report this Post to the Staff
