I believe I found my first 2011 ddo cent, but j am unable to find a matching listing anywhere and the doubling has very minor spread apparent in the 2 and zero the best. The 2 has notching on the bottom left but it's difficult to see in the photo.
Here's one to check out . You need to plumb that image up . http://varietyvista.com/01e LC Doubled Dies Vol 5/2011PDDO002 cent.htm
Unfortunately, I'm currently on vacation, but I'll try to snap a couple new pics when I return. The listing doesnt 100 percent match, but the spread is similar.
