1979 S Susan B Anthony Dollar: Strange(?) S Mint Mark.

Those are definitely better pictures. One thing to do would be to look at the gallery of mint state coins on PCGS, and see if you spot any similar S mint marks.

I agree that it sure looks like damage. Sometimes mintmarks seem deformed due to die chips or doubling in many different forms, but yours doesn't really look like that.

It appears to be damaged, I cannot tell if this is a type 1 or 2 MM.

First and foremost, I want to thank all the contributers for your opinions and comments. I see that the consensus is that what I am seeing is PMD.
A big shout out to @Errers and Varietys for the link to explain what PMD stands for, Post Mint Damage!
I also want to give a hardy THANKS to @Brandmeister for the link to pcgs images. I went through all 52 "S" pictures, LOL, #41 is a P and found that none of them were what I would call clear and distinct S mint marks, in fact some were nearly un-readable. Neither did any of them match my S mark. Having studied all 51 images of the S mint marks in the highest resolution by clicking the download in the upper right corner and place the magnifier over the mint mark and click, I'm fairly convinced it is NOT anything special, but is likely a messed up mint mark from minting. Again, after examining all 51 images, virtually none of them have a clean S, in fact the P on #41 is a cleaner mark, IMHO, than any of the 51 S marks.
Please, I encourage you to look at all 51 of them for yourself and see how many of those you feel are from the mint and how many may be PMD's. I am currently under the impression that none of those mint marks are PMD, but I'm open to your opinions to change my mind!
Along those lines, I only found 2 images, # 9 & 10, to have the same mint mark. All 49 of the remaining S's were differant, ranging from #25 that was IMHO the worst to # 15 & 16 that were amoung the cleanest. #'s 3, 7, 8, 25, 27, 34, 35, 37, 39 and 47 I think had some minor resemblance to the coin I have.
Thanks again for all your help and comments!

LOL, I think Google AI sent you on a wild goose chase. You have a business strike 1979-S dollar. To the best of my knowledge, there is only one S mint mark punch used on those coins.

The type 1 and type 2 San Francisco mint mark is restricted to proof strikes only for 1979, at least for SBA dollar coins.

oh yeah, I forgot about that - thanks Brand!

LOL, I went through three rounds of trying to buy a 1981-S type 1 and 2 proof nickel. Ultimately, I ended up with three or four of one type and zero of the other, and put that folder on the shelf. Those are harder to tell apart, though. =)
