Is there a list with images of the known rpm's for the 64 D Jef nickel

in Q & A Forum
I found this1964 D Jefferson nickel with a definite D/D RPM but unlike the ones ive found images of. I've posted pics here for any help on this one i can get. However; more importantly, is there site for nickels similar to Mr. Daughtreys' Coppercoins.com?

I'll agree with the MD (what's the P?). But here's a list of RPMs anyways..........

And a good read regarding Machine Doubling...........

Try to post coin related things on the US coin forum, that way they get more traffic.

Sorry about that. I wasnt aware it was the wrong place. Just out of curiosity though what place is this that makes it not coin related? I had questions... that's the first word in questions and answers, correct? Thanks for the heads up though, I appreciate it.
There is nothing wrong with posting in this forum and you will get answers, I think that what Ownerofawheatiehorde was saying is that US coins would get more exposure in the U. S. Coin Forum. There are a lot more members that follow that forum than this one.
In this case, there is no need to repost the question - the answers given are correct. The mint mark has machine doubling, and the varietyvista link supplied by @Steven59 is the right place to go to see images of known RPM varieties for the date.
