It probably will be the only one you find as damage ( which is part of the mm situation) and some mechanical doubling. The different mint marks of a specific year/coin is almost always the same size /font.

 

Thank you kindly. I have much more to show.

How about this 1991 d ddo, very obvious. What do y'all see?

That is a form of split plate doubling. It is a disturbance between the zinc and copper.
