Well there is a weakened area on the eye and nose, that looks like the die had an issue with Feeder Finger Damage. But a clash may have affected that area after the dies fields were reduced and could leave a mark on that area. So I fell that is what you are seeing a die clash line. (I've got images of the reverse Feeder Finger Damage, but not yet seen it on the obverse, which is possible. Just haven't seen it yet)
