Not sure what info you are looking for but don't forget they were hand punched and sometimes the punch was worn or the mint employee might have punched it a little deeper than on previous dies. Some years had more than 1 different style punch so any of the above can make the mm appear different from other dies. If this is not what you want to know, please be a little more specific with your question.
Thanks for the information and replies. I really didn't know how to phrase my question, but the mint mark looked off to me. I thought it was probably normal, but wanted to ask to be sure it wasn't an S over S or even a S over D. Again, I'm new to this and my equipment and eyesight isn't the best. I added a couple of additional pics.
