Found this penny while hand-sorting; not sure if it's worth keeping:

The reverse looks perfectly fine, but the obverse has a very obvious ridge on the left side (I first discovered the ridge by feel). The diameter appears to be uniform standard penny size all around (don't have a caliper to check for sure). If anything it looks like the coin was struck at an angle, with the left side being too low.
