1964 D Quarter With Triple RPM?

Im not seeing a RPM. There aren't any on doubleddie.com or varietyvista.com that are close to this. I do not know much about Washington quarter rpms, but it seems Machine Doubling is fairly common in that area of the coin.

I agree that there is some Machine Doubling but many of the RPMs on variety vista or Wexlers has MD. the MD on the the devices below the mintmark show it to the left of the coin. But I don't think that explains the rest of what is going on.

As Coop said, is die contact marks meaning the mintmark is higher than other detail around it(was punched in to die deeper than incuse details.)

I guess I should have said coin contact. Sometimes coin ejection contact can affect devices. Hits on something while the coin exits the chamber. (could be Feeder Finger Damage to the coin from contact, or something on the way out of the chamber)

Generally, not always, the punches made for mintmarks are the same physical sizes and shapes. RPMs are formed when the punch is rotated (turned) or laterally moved from the original stamping. Sometimes it is an intentional movement necessary to correct improper placement or depth, or is accidental during the "second tap" of the punching to make sure of accurate depth upon the die face. One oddball year that comes to mind is 1964D's, a "skinny" punch and "Thick" punch were used.
