This is my first post in quite awhile, so forgive me if I miss some proper technique or etiquette for these forums.

I've recently picked back up my search for error coins and have found a few interesting ones recently. They may be nothing, so bear with me. I'll post them all in separate threads if that's the best way to do it.
Anyway, first up is a 1992 nickel with a deformed "C" in "FIVE CENTS" on the back.
http://img.photobucket.com/albums/v...edletter.jpgI've never seen a "C" do this on a coin and was wondering if this could be a deformity from the manufacturer or if it's most likely something caused by trauma after the fact. I don't see off hand how any damage could cause this, but I suppose anything is possible.
What are your thoughts?

edit #2: I thought this closeup view of the "C" might be helpful. Photobucket kindly squashes original pictures.
