1964 D Quarter Mint mark ??

Hello everyone, wondering if the mint mark is just doubling?

Just a thought, and not sure if I'm off base, but the mint marks, at this time, were hand punched into the dies. It's possible that the worker, working the 'punch', was a tad bit off with his weapon......

 

Always check for the Type C 1964-D reverse. As for the MM,
I read that it can be RPM but not DD.

 

Type C quarters are hard to find with photos. The pictures have to be pretty spot on. I think the D mintmark may be an RPM with a side of machine doubling. The first mintmark looks south of the second mintmark. There are a couple known RPMs for this date.

Check the link at the bottom of the page. It looks like it may be WRPM-007. See if your coin has any of the die markers. If not that one maybe one of the others.

Then why is the rest of the coin not RPM'd? I find it hard to believe that only the mint mark could be Rpm'd

I think your right. I got the exact same answer from a friend. Thank you @gronnh20

 

You're.....

 

Are you saying he had a few drinks at lunch.

 

I don't know what caused that mint mark but it's pretty cool.

 

RPM means repunched mint mark. How could any other part of the coin be RPM?

 

RPM means Repunched mint mark. Sorry @Michael K. Didn't notice your post until after I typed this.

 

I was about to add the same thing. Both of you are faster on the draw than I am.

 

The reverse looks more like Type A to me.
Compare the markers, one by one.

 

All this time I thought RPM stood for..
Revolutions Per Minute

 

It does, Sir. It does.

 

I still use my turntable almost every day.
Records sound MUCH better than remixed washed out CD's, even if there are scratches.

 

Repunched Mint Marks was a totally manually process.

The technician, during die maintenance would take the die, set it in a vice and pull out a small hardened steel rod which had just the mint mark on it.

They would then under magnification slot it in the current mm and hammer the rod to make the mm deeper. Sometimes they were off and you would have multiple shifted images of the MM, ala RPMs.

Of course, they may have buffed the die before the MM maintenance too.
But RPM, as the name implies, is solely related to the Mint Mark.
