I've only found a couple of these. And like everyone else I dismiss them as hub doubling or mechanical doubling. But after a little more research I find out there are considering these doubled dies. Supposedly at first they thought the same thing mechanical doubling. But considering the striking factor they eliminated it and made it a doubled die. (What do you think.)
Just came across another one. I have noticed John doesn't have any of these listed. As doubled die. Going to send this one and to see what his opinion is. I personally believe it is hub doubling. Or a plane out damage die.USMC60
