As far as the rim goes, your'e seeing a Mis-aligned die strike (MAD) if the reverse is normal, or if the reverse is like the obverse, you have a slightly off-center struck coin.... to CCF
More of a tilted die issue. That caused the fin that was there on the edge of the coin, but now is flattened. I feel that just as Machine Doubling is caused by a loose machine, that the tilting of the die is also the same issue that happens on some strikes and varying.
If someone gets a OBW roll of examples of the Machine Doubling examples and we see the tilted die issue on some of them, and not on all from that same die pair, that would help confirm my theory.
