Help with 64 d quarter mintmark

I am sorry for the poor photo. I am a retired photographer, but I used film, and am a Luddite with computers. Please blow this photo up and look at the d mintmark. Probably nothing, but looks like a blob. Just going through some coins and thought this was unusual. The quarter is uncirculated. I would appreciate your opinions as you guys know what you are doing. Is this worth looking into any more. Thanks in advance.

Looks OK to me with a shallow center. If the center of the "D" is completely filled, it is also OK and nothing special. This is a fairly common thing and can have several causes.
Rare "rotated coin" variety. (

Nothing special!
Thought so. Proof that if it is rare, I ain't got it. Thanks for the info.
Dont give up smudge who knows the next one could be it!
Keep looking.... that is the only way to find the rarities...Cheers, RickO
There are several different mint mark placements and a few different looks to the mintmarks for the 64d quarter. The filled d mint mark is common.
