@Shrews1994 It's impossible for us to tell because you took the photo from a position slightly angled from the south, and the RPM is hidden on the north side of the mintmark. Chris
Notice that your coin shows shelve like appearance around ALL the date and MM. And your image is taken slightly lower thus *not showing* the RPM which is on the top of the S. Notice the RPM is on the North side of the MM. And subsequently and totally separately, the date doesn't have any shelf like appearance of doubling. You'll have to retake your pictures from either straight above, and/or from slightly above looking back down to get the *exact* comparison .. and not something that kinda looks like it.
The date looks like Mechanical Doubling. Could be the same effect on the Mint Mark. Together with a small Die Chip. IMHO
just remember, there's not just *one* machine making these coins. They regularly ran .. what .. 3 - 4 machines at SanFran with one "supervisor", with multiple people running batches of machines of the 261 million made in San Fran?? And the mechanical doubling .. I mean those shelf like edges around the date and mm, and the 2 die chips are indicative of a later state die of one of those machines, whilst the die was used for a short time (up to 3 days .. from an entire years production) .. or something like that ... so with the RPM you are looking for one of those many dies that was repunched, and used for a short period of time out of all those hundreds of dies used throughout the entire year.
Mechanical Doubling and Die Chips !! don't forget to look around .. like the date which has the same indicators as the mm (hint: that's what I was pointing out ...)
That darn S mint mark all ways chop full of die chips and variations. Earlier die states are the one to look for RPM's
