Can you see a slightly doubled column on this 1996-D penny? I am not sure if these actually exist, but I am interested to see what this doubling error is

I use varietyvista to help identify mint errors and doubling. They also have a VERY good section about the minting process and coin making in general that provides a great deal of insight as to what, why, and how! Just click on “What are die varieties”
