Need confirmation on this 1920 S RPM 1

[WaterSport]

Seems Wexler is the best resource at this time to ID this rascal. It has machine doubling. But I think the die dot in the upper loop of the S confirms its RPM 1. What says you ?

Remember, I'm a novice at best, Bob but I say no. I did not do an overlay but yours looks slightly more southwest. Not for sure but I think Will did a study that decided the master die had the dot. Here is a link to the mm. (http://www.varietyvista.com/01a%20LC%20Doubled%20Dies%20Vol%201/San%20Francisco%20Mintmark%20Styles.htm) If I didn't know any better, I would say the Wexler and VV dies were different from each other too.

I think Jons onto something.

I also marked up your image of the MM to show how the left edges upper loop of the primary and "secondary" mm seem to go in different directions than the image on DD.
See what you think.

Thanks folks- I will put it in the wishful thinking pile.
