    Found this video on Youtube, thought some of you might find it interesting as to HOW some of the copper coins become silvery or golden in appearance. It's short, I found it interesting, easy and enjoyable and felt I wanted to share it.

    Use a 1943 steel penny using just the zinc dip and you get a real nice new looking steel penny :D

    Yeah, I think this is what they mean by "reprocessed steel cents". :)
