1969D Jefferson Nickel, dual denomination RPM

When I first picked this up, I assumed it was a San Francisco. Then saw the Denver mint mark, and thought, well, I know this came from San Francisco and I’ll likely find a dual denomination rpm.

Hey there, are you meaning a “DMM”Dual Mint Mark”, or maybe OMM” Over Mint Mark” Because a Dual Denomination is where a coin is struck , let’s say as a Nickel, then was Struck again by a different Denomination Die like a Quarter, if its one of the former you mean, I see neither DMM, OMM and certainly not the Dual Denomination. Maybe more information would help. I do see a lot of Die Polishing marks.

I'm sorry but not a dual denomination nor is this a D/S Mint Mark....
