1964 Nickel D/S/D?

I believe I see an OMM with the D over S over D. 1964 NICKEL 2.jpg 1964 NICKEL 1.jpg 1964 NICKEL 3.jpg

Here are the known documented OMMs

1955 through 1967 there were no Jefferson nickels minted in San Francisco.
I am pretty sure Denver mint did not have an S mintmark punch laying around in 1964. The S mintmark had not been used for close to 10 years by then.

Heres a listing of the RPMs for Jefferson nickels.
