1895 Cn 8R - Genuine?

In another recent thread, swamperbob mentioned that he always looked at the edge of this type first in trying to determine authenticity. I picked up the pictured example last week and didn't pay much attention to the edge, but now wish I had, albeit everything else looks good and it wsn't an expensive purchase. But there are a couple of suspiciously "mushy" spots on the rim that give me pause. Also, the weight, at 422 grains, is at the upper limit of what I've observed for these. I may actully have to determine this one's specific gravity to get a handle on it.
