Is This A Double Die?

The little bit of doubling that is visable in the second pic looks like like Strike Doubling to me,,

if you can picture a wheel on an axle then the process of how the doubling is most evident on the periphery of the coin is more understandable,,

the die is mounted in the holder on a center pin, if the die rotates slightly on impact with the planchet the outer edge will move much farther than the center.

while the center does move and minute doubling will occur toward the center the amount would be significantly less.

your coin shows a very small movement on the outside details,, the center would be almost imperceptable.
