    Split plate doubling?

    Is this split plate douling or is there some splits that im seeing on the S and T of States? There appears to be some sort of doubling in the middle of the S and the T as well as some present on the D of United. Have i been looking too long or do you see it too??

    It's not split-plating. It's a mild form of MD or ejection doubling. What year is it?

        Split plating is just that, the copper plating splits and the zinc below is exposed.

          Great photos. Unfortunately, I agree with Jody...some form of MD.
          Keep up the hunt!

              This is the page on error-ref.com that deals with split plating doubling.

                  Yep. Here's my example of split plate doubling: The whole way around the memorial and toward the rim side of almost every single horizontal letter part and column on the entire reverse.

                    WOW... Thats a pretty cool example... Do you think at one time these coins actually had the plating around the edges of the devices bt it just fell off the coin?

                      I don't think it fell off at all, it just split. Think about it logically. You start with a FLAT surface. When you add relief to it by striking a design, you are actually increasing its overall surface area. That's fine and dandy on a solid metal planchet, because it just takes the needed material from the rest of the planchet, but on a PLATED cent, the extremely thin plating cannot stretch to accomodate the increase in surface area, and is therefore prone to just splitting around the (now) raised areas due to stress. With how thin the plating is, I am surprised it doesn't happen on all of them, to be honest.

                        Split plating can happen on various locations on Zincolns:
