1960 D Lincoln Cent, not sure about this. The D looks like another lightly but I could be wrong. So some help from y'all, feedback, THANK YOU VERY MUCH.
Until 1989, the mm was punched into each die by hand. The depth and location can vary quite a bit. Your cent is normal
If you don't think you captured the photo correctly. Here is a reference to the 60 D RPM's.. Use the Mintmark placement to help you. There ae 113 of them for the Date and MM. http://varietyvista.com/02b LC RPMs Vol 2/RPMs 1960D (1-60).htm
