Hello all, can anyone help me out here. I was looking at my PROOF SET, and noticed something under the (S)..to me it looks like a (D) mint mark. But there is definitely something under that (S). Here are a few pics. So you can see for yourself. Thanks in advance . I mean 1968 (S). Not 1969
ALSO when you upload, can you click on the 'Full Size' icon, makes it easier to see what you're showing us. Thanks
All these pics are not good to see the Mintmark . You need a darn Microscope my friend . I tried to enlarge and crop but failed because it was too blurry .
Those are tiny chips in the creases of the S. And realize what an S/D is as opposed to an S/S. An S/D is a D die punched for a D mint that was over-punched with an S for an S mint. That's why those types are virtually unheard of.
