Looks legit to me. You should research this error for photo confirmation since it should be a known DDO.
The doubling I see seems flattened ( indicative of mechanical doubling), Since this was still in the multi squeeze die hubbing era they should have more 'rise' to them. Most DD, show both parts as raised , sometimes to the same height. I assume that you see LIBERTY as having doubling, but if you look at either side, neither of the width of that portion is full size. both parts of the doubling are smaller than the original width, another sign of mechanical or strike doubling damage. Same is seen on 'WE'. So from the photos I think it is MD. Jim
That's a tough one I would try and match die markers from some of the well-known sites such as http://www.varietyvista.com as @SlipperySocks suggested. Good luck.
You must have me confused with someone else.... Do the research and become your own Master. Then come back here and share what you find so we can learn with you.
