Let's not be hasty in calling that
Machine Doubling. The earlobe is a known location for jolted-type class 9 doubling on Lincoln cents of that era. Compare the known 1997
DDO for Lincoln's earlobe with this 2000 cent. That is darn similar. There is a more extreme version from 2006 where the earlobe is separated from the ear. Both varieties are official Fivaz-Stanton
DDO listings. You can find several less extreme doubled earlobes on Variety Vista and Wexler's doubled die index for multiple different years in 1999-2006.
If someone stumbled across an unlisted
DDO on a
Lincoln Cent of that era, the President's earlobe is almost certainly where it would be. I'm not saying conclusively
DDO vs. MD, but I think we need to be systematic with this example.
