2. Please remove coin from the holder unless it’s US or an official mint case or unless it is graded by a grading service.

3. Images should be taken by a camera or cell phone camera, we ask that members don’t use images through a microscope screen.

Not to me, I don't see anything evidence in the opening of the D and when the mint marks get mashed during circulation they can look like this. I suggest comparing them to coppercoins.com and looking for die markers.

I agree with Daniel. And looking at some of the nearby devices it appears like there may be some mech. doubling occurring. And sometimes it is hard to tell with a single image. But having the coin in hand, you have a better view to help determine if the marks around a MM are actually from an RPM, MD, die scratches/gouges, or circulation wear.
Be sure to Visit the coppercoins.com site. Very helpful with images of most known varieties. Thanks for posting and sharing.

I'd say the 1970 is the most obvious out of the three. Definite RPM

We're seeing too many image artifacts to be certain.
