Alright folks, I believe I have found a DDO, but need some opinions. This looks like a DDO error to me but I am no expert for sure! WOuld like to have your opinions on what I have here. It is AU and Brilliant appearance. Thanks in advance. I affectionately call this my "Double chin" Lincoln LOL
Doubled Die is falls into the Variety Category. Not Mint Error category. Here is some great information - https://www.ngccoin.com/news/article/1655/Variety-versus-Mint-Error/ And https://www.pcgs.com/news/mint-error-or-die-variety
Which class dd do you think it is. By knowing the DD classes it would help you evaluated this. Looking at this http://www.varietyvista.com/01a LC Doubled Dies Vol 1/DDO 1956-D.htm Would help too But you image seens to show flat, shelf like areas. Which would be MD.
