First off, I am a noob, so never mind what I say. To me, it looks like the lowest part of the lobe is where the ear would normally end, so there is a dent above that.
My pleasure. One thing I look at is a line from the bottom of the lobe to the top of the shirt collar, the hair is above that line and below that is neck. If that isn't the case then I look closer.
Here's what the 1984 double ear looks like, I own three of them, two of them have the marker, under Lincolns chin
Rick, I don't see the doubled ear there... and Happycoins...it looks like your coin has mechanical doubling.
Their all double ears, my microscope only take photos to 250x after that, it starts to distort, heres the photos of the markers under the chin on the two that have it
Heres a photo from pcgs, the marker is a ball under the chin, if you go on some of the error grading companies don't even talk about the ball under the chin for a marker
Rich You may have the 'markers' but I don't see the doubled ear on yours. I don't think they are the doubled ear.
When they get back for grading, then I'll repost them, heres some photos of the ear with no saturation, or color
Now wait a minute...markers? chin? A double ear example is Cherrypickers FS-037, Coneca DDD-001, Poter VCR#1/DD0#1 and Wexler WDDO-001, I am by far an expert, but come on,..Keep searching, Ref: Page 81 Strike it rich with pocket change. Author--Ken Potter and a Dr. Brian Allen---good luck
