1974S used 2 different mint marks types. One of them was a defective punch. The first 3 you have there are just banged up, worn mint marks, I'm not even sure which type they are from your pictures due to the damage. But what you have on #4 is definitely from the defective mint mark punch. (I happen to be doing a study/article on this very punch as we speak.) The damaged punch is characterized by a split upper serif and curl (1 and 2), a blob at 3, and also a cavity right in the middle at 4. This is NOT an rpm. All coins bearing this mint mark have those same characteristics. Photo by Ray Parkhurst.

*Important Note* There IS an RPM listed by coppercoins that had this defective punch. http://coppercoins.com/lincoln/diestate.php?date=1974&die_id=1974s1mm001&die_stat e=mds When you look at this link, you will see an arrow pointing to the top split. That is actually NOT part of the RPM like it suggests; however, the doubled serif at the bottom is NOT characteristic of the defective punch, leading me to conclude that this listing is in fact an RPM. Hope that makes sense.

Thank you again for the very informative explanation on what my coins exhibited.
