No variety exists on brianscoins or whatever the site is called that Wexler directs you to for nickels, but this thing looks really doubled on the obverse to me... I’m almost certainly wrong tho lol.
I'm no expert, but that looks like mechanical doubling to me. That is just my opinion, though, so wait until an expert confirms my theory. I am like 99% sure, though.
Nothing listed here. http://www.varietyvista.com/04b JN DD Vol 2/DDO Listings.htm Doubling is in line with the radius of the coin, not a good sign of DDO.
