I have this 1963 nickle with what appears to be 2 separate edges on it. One on top of the other. I tried to get a clear pic but my camera is not the greatest...can anyone tell what this is or what happened to it? Thank you! Gary
All right guys, give Ron a break, it's his first post. We usually call the "edge" the rim. If it's only doubled around part of the perimeter of the rim and only on the obverse(front of the coin) then chances are it's a mis-aligned die. They're very common and there's no premium for them. Welcome to the forum and keep searching and asking.:smile
The edges are slightly raised on the planchets before the strike, so you either see that one because of a slightly misaligned die, or it could be a collar clash. There's really no premium because they are pretty common.
No a railroad rim is the result of a partial collar and actually shows on the edge of the coin and not the rim. The picture in the OP is not clear enough to tell what is going on. Could just be well struck with a high rim, could be a finned rim, could be the result of a collar clash, could be a dryer coin.
