If you don't enlarge a couple of the pics I believe I see what your talking about and coop and crazybo are right it's just some pretty severe
Machine Doubling on the left of the devices especially the A's in states and America and the M as well. A big indicator is the thinning out of the letters. It's hard to tell the diff when you're just starting out but like coop said, the part that looks doubled is lower than the main letters like a step down. If you were able to look at it from from a 90° angle it would look like steps. In the doubling you are thinking of, the doubled devices would both be the same height. Check out doubled die.com and study the examples and you'll be able to see what we're talking about. I just started a few months ago and have only recently been able to really discern the differences between all of the doubling causes. You have to make mistakes to learn from them and this is def the place to learn. Good luck in the future and happy hunting.
