Doubled Die? 1976 Mt. Rushmore 200 Year Anniversary Medal

This one looks to me to be a doubled die, both obverse and reverse. Not double strike or Machine Doubling, because there are at least three examples with identical "doubling." I just received one, have another on order, and there is a third one still for sale on ebay. I'm thinking maybe the whole run has doubling, like the 1946-S half dollar.

Here is the ebay number for the second one I bought, but haven't yet received: 92122927952

Here is the ebay one still on sale: 131935180363

Note that the "doubling" on the reverse is on the AM in AMERICA, final close-up photo.
