Came across this cherry picking. I can find no DDO or variety listed in Wexler's Die Varieties. True DDO, machine error, etc.?
If it were a true doubled die, the digits would be slightly thicker than normal. I don't think it is a DDO. Chris
Here is Coneca's new e-book for doubled dies. Check there , and check Coppercoins as well as Wexler's files. http://www.varietyvista.com/01b LC Doubled Dies Vol 2/DDO listing.htm
