Shoesnsocks Valued Member United States 114 Posts	Posted 03/01/2018 5:40 pm I'm not sure this is an error or not and havent heard of this happening on a coin but it's the first time I've seen it. This extra rim goes around the whole coin evenly and is on both sides. Report this Post to the Staff

Shoesnsocks Valued Member United States 114 Posts	Posted 03/01/2018 6:44 pm I guess calling it an extra rim is probably not the right way to describe it. It's like the raised rim of the coin has a slightly smaller diameter than the edge of the whole coin, creating a sort of shelf that sits below the outside edge of the raised rim.

Crazyb0 Rest in Peace 10197 Posts	Posted 03/04/2018 01:02 am The planchet, prestrike has an upset edge, a "pre-rim" so to speak. when struck between the two dies metal is forced into the devices and because of the "rim offset" on the dies outer edge will form the rim in contact with the pretension from the collar. If there is not enough pressure on the strike, details are incompletely formed, shallow letters and the incomplete formation of the rim.

Shoesnsocks Valued Member United States 114 Posts	Posted 03/05/2018 12:35 am Super interesting. I might need to watch a vido before I can understand that though. Report this Post to the Staff
Shoesnsocks Valued Member United States 114 Posts	Posted 03/05/2018 12:38 am Oh OK I think I understand a little more. So the planchet had a rim already but a weak strike caused the final rim to be incomplete? Report this Post to the Staff
