I feel it is more of a Machine Doubling issue. Keep in mind the 1968 cents had the devices on the rims because of a swollen master hub. (replaced the next year)

I've seen this before on a 1982 quarter that had the same issue that year:

Note the head and other devices are enlarged, fix the next year with a new master hub.


You can see where the MD pushed the devices past the rim area.
So I feel that is what we are seeing on this cent, the MD pushing the devices outwards, almost create a Rim Fin, but looking more like damage to the coin.
