Ball Serif S mint mark. Ordinary, except for that top spot where it was grease filled or took a circulation hit. The ball serif is an odd mark that was only used for a few years. Unlike most of the others, it looks sensible when turned upside down.
It's common for the area between the ball serif and body of the MM to be weak or missing. Seems like the punch was weak there. Die work to flatten the field after a clash or whatever will often remove that area, and die wear often obliterates it as well.
