Note the stars on the first image. That is showing Machine Doubling on these. So the other areas maybe partially MD or coin damage. I'm not seeing a doubled die on your coin. Same on images #2 & #3, Machine Doubling.
I suspect the double nostril is a hit that created something that resembles a second nostril. Given the distance between the two, if it were die doubling I'd expect to see a similar spread at the eye, but I don;t.
