Hi guys, I brought this subject up awhile ago. I bought this 1964 Mint Set, specifically for the Quarter mint mark appearance. I thought for sure, this was at least the RPM. To me, the Mint mark actually looks to be a "triple RPM"? Notice the inner doubling as well. Yes or No? Thanks guys. 
Sorry Guys for the Blurriness

Variety Vista doesn't list an east or east/east rpm for this date.

It might well be an RPM for all i know, but it appears very "flat and shelflike", which is a key indicator of MD.
How cool if this ended up being a "Discovery Variety"! Stranger things have happened. Either way, gotta love this kid's enthusiasm.
I kinda like it
I don't think it is a repunched mintmark. Look how narrow the right side of the raised portion of the 'D' is... indicating a portion of it was 'smashed' down making it narrower. But that is just my opinion given the photos. With better angles and lighting... might be able to make a better judgement.
That is not an RPM
Sorry
I get it in thinking it is the dreaded M.D. It's just I don't ever noticing any machine doubling with multiple layers such as my coin has? Thank you all!

I just pulled out an Unc roll and the first 15 coins have some sort of machine doubling, here are 4 of the better ones.
Sorry the photos aren't better but I think you get the idea.
So the answer to your question is yes, it really is machine doubling.
Thanks. It's the "Triple Mach. Doubling" that gets me. Your's is the common single layer M.D.

Please only remember my opening Sig Line.While machine tripling is not as common as machine doubling it is not all that uncommon. Your coin is a nice example with nice separation, but it is still just chatter from the dies. Machine doubling, ejection doubling, strike doubling ... so many names for the same effect. The die got into a nice little rhythmic chatter.
The above coin is not an RPM Joey.
Tripled machine doubling would be 6 MMs.
I think yours is MT - Machine Tripling.
AS others have said, it's MD. I have seen many 64-D quarters with the same characteristics.
I think this kid is older than I am!

One more vote for machine doubling/tripling....Cheers, RickO
