    Crazy, Deep azure blue PSD on this 2007 Lincoln cent

    I saw the reverse first and noticed a little bit of corrosion on the rim. When I flipped it I was really surprised by how deep the colors are. The colors are so crazy I had to post it. Some type of caustic substance creating these colors. I'm guessing it's reacting with the copper plating.
