Please post clear photos of both sides of the entire coin along with the photos of the area in question. It helps us determine more accurately what you have. Thank you.
It does look like MD to me. It flat and shelf like, but the T in Trust does show some DD split serif very prominent. Im thinking it could be both MD and DD at the same time. Well, unsure about this one. Wait for some other to chime in.
I may be wrong but I believe I see the same thing, the "notching", on the I, N, D, W, E, T and R in IN GOD WE TRUST. I can't be even reasonably sure about anything else.
I notice on some coins when they are really "shiny" that one of my cameras tends to make coin devices look this way. Ive taken some pictures that look exactly like this only to use an old magnifying glass and the "doubling" just vanishes. Im not saying this is the case but on some angles up there, the doubling effect is eliminated and you cant see it. How does it look to you just using your eyes under really bright light? does it still look doubled?
