Back to looking at my pennies today after a pause and found this one in the first set. It is not a particularly nice coin, but what caught my eye were what appears to be 2 cracks on the reverse. What I believe is a crack on the left side runs from the rim to the top corner of the Lincoln Memorial between I and T in United. The second crack runs from the rim through the vertical section of the C and a little further toward the memorial. I don't see any obvious signs it runs along the top or through the memorial. What would this type of crack be called? A Pre pre cud?
