Just found this inverted ball S serif with the ball on the bottom. Kinda cool because I haven't found any listings for it yet!
@paddyman98 I'm going to have to agree with you there it doesn't look its a little flat on top. Other than that it looks like it's inverted IMO.
These are the images I was comparing to from Wexlers IMM list of the 1946 S . They look very close to the pics of my 69 S aside from the top of mine having take a hit and flattened out. Normal↑↑↑↑↑-----Inverted↓↓↓↓↓ https://doubleddie.com/1655200.html
You have a point on the inverted S but I would call the adjuster on that hit though . LOL Whats that called " Hit and run " ?
The mm style for 69 is what is called a Tall MM or MMS-008 Image taken from VV http://varietyvista.com/01a LC Doubled Dies Vol 1/San Francisco Mintmark Styles.htm I still see nothing wrong with your MM except some damage as Paddyman pointed out.
