Not sure if this is the appropriate forum, but I haven't seen a thread anywhere on damaged coins. I seem to find quite a few of them. Here are 2 that I found particularly interesting. Just thought I'd share them. Looks like lamination to me. Looks like someone has used it as a pin cushion.
This should be a fun thread ;D, here's one i recently found. Looks like someone used sandpaper all over it xD.' Be cool if these coins could tell us how they got this damage!
