tropicalbats Pillar of the Community United States 6116 Posts	Posted 03/13/2018 3:42 pm For most of the double struck coins I have there is a big area mooshed out. So here is my guess on this one: double struck in collar. But whatever happened it bent the coin a little and put a small knick in the edge two places across from each other. I saw a coin like this a while back so I know it's nothing new but I don't know for sure what to call it. Again, thanks for the help with the error coins. Sorry about the bad photos but I am imaging a lot of Lincolns and didn't want to change my whole set up for just this one coin. Report this Post to the Staff

tropicalbats Pillar of the Community United States 6116 Posts	Posted 03/13/2018 10:11 pm Okay, so first strike in collar, and second strike out of collar. But if the coin is struck out of the collar how does it still maintain its roughly quarter size? All the second strikes I am familiar with really hit the coin and create a flatter, wider area on the second strike. Can you go into a bit more about how this all works as I'm not there yet understanding it. Report this Post to the Staff

tropicalbats Pillar of the Community United States 6116 Posts	Posted 03/13/2018 10:59 pm Got it a long time ago in a big lot of coins that had a few errors mixed in (separated but unlabeled). This one was my favorite but I never knew how to label it correctly and so thought I'd post it and learn what's going on with it. Report this Post to the Staff
mikediamond Pillar of the Community United States 2738 Posts	Posted 03/14/2018 09:59 am Many off-center strikes generate minimal expansion. Degree of expansion is dependent on striking pressure which is, in turn, largely dependent on minimum die clearance. This coin additionally shows a "foreign object chain strike" on the left side. The left side of the coin abutted one of the two feeder fingers that cradled it. The expanding coin metal flowed against the expanding metal of the feeder finger. This expansion also pushed the other side of the coin into the opposing feeder finger, generating a dent in the edge. The latter is a form of "intra-strike damage". Error coin writer and researcher.
