if I didn't know better like I do now, I would have thought this was doubling. I thought this was a good example of extreme machine doubling. Thought I would share.
@Sheila Ruley I'm not so sure that all of your images are the result of machine doubling. Have you checked it against any of the online sites? Chris
I wanna say it is die deterioration doubling. Check out the nickel shown here http://www.error-ref.com/die-deterioration-doubling-raised/
I can't match it up with the lines going down the middle. Especially the next one I posted. The 1988. Check that out on this thread. Any other websites that may show near the same kind I have? I googled it and couldn't find much.
I'm quite sure it's a form of strike doubling, not only the push as shows on certain letters, but what you're talking about as well. I know somewhere this has been discussed or explained, but damned if I can recall exactly where or when. That said, it's certainly neat, no doubt.
Can't say I've ever seen this before, not even after 10's of thousands coins, and I've seen my fair share of extreme machine doubling also. Never heard of push doubling either, so I'll have to check that out. I'd hang onto the second coin until you can get a definitive answer. Maybe send Wexler a note along with your photos.
Of coarse it's possible. Hub doubling is part part of the die while machine doubling is from the die bouncing during the strike so yes a die that was made from a doubled hub can bounce and create machine doubling as well just like any other die.
