Considering how the San Francisco Mint didn't strike coins from 1956-1967, it's impossible. Possible for earlier Franklin halves though.
Some believe 1950-D RPM-001 to be a D/S but without conclusive evidence it remains a D/D.
VP-001 is the same as RPM-005 on VarietyVista. Note it says it's repunched northeast of the first impression, so it would appear like a secondary mintmark is southwest of the stronger, final mintmark punch like visible in the photos for RPM-005. Regardless, the doubling on your coin is to the northwest.
Your coin may potentially be MD, looks like there is some MD going in the same direction on the ES in STATES in your second pic.
I see no images of the devices on the top above the mintmark area? I did a view on examples of PCGS images to see if there was a damaged mintmark punch issue on that series. None. But I did noticed a lot of Machine Doubling on these examples. So if the tops of the devices has MD on them, that maybe the cause?
