Welcome to CT. As stated above, the photos aren't definitive enough to tell much. Maybe you could post a better, in focus, close-ups of the date and MM? And thanks for posting the photos full image.
Looks like MMA-004 (trumpet tail). 1946 had 3 possible S mint marks. The MMS-004, MMS-006 ball serifs, and the MMS-007 sans serifs. It also had an inverted MMS-006.
