This looks like a combination of mint errors. One reminds me of a strikethrough and one like a cud...but I'm still a novice at error coins soo... I thought I'd ask you guys. This Jefferson has this weird pattern struck on the reverse, like fabric. Maybe it's just a badly damaged error nickel? The nickel is not perfectly round either, which I'm sure you can see. I'll take shots of the edge if it would help. Thank you very much for any responses, you guys are awesome.
