Always best to post pictures that aren't upside-down and out of focus, that way we can actually see the doubling. You can check here to see if you can find a match, here to learn about other types of doubling, here if you want to learn how dies are made, and here to learn more about doubled dies.
The attitudes I have represented in other recent threads. I would respond to the OP but it seems others have gotten it well covered.
I mentioned nicely to post clearer pictures. When we enlarge your pictures they look blurry. Some other member who posted just likes to start trouble. I apologize for that.
Taking pictures is really tricky, I can't do it worth a carp. What are you using? If it is a cell phone, members here recommend putting the phone on a stable base like a small box and lighting the field well. What works for me is to put the phone in one of those thingies you can use to stick your phone to a windshield and put the coin on a slanted base of some kind so that you are at 90 degrees to the coin and stable. BTW welcome to CoinTalk (sometimes seems like PlainTalk)
A large number of silver Quarters from the '60's show mechanical / ejection doubling on them, especially the reverses, including the D Mintmark. (especially 1964-D's) I'll stick my neck out and say that there is a 99.857% certainly that the OP's coin(s) have this type of doubling.
maybe some help .... 1 - go to a well lit area. The brighter the light the faster the "shutter" speed of the camera which minimized motion blur. 2 - put the coin on a FLAT surface (not your hand). And take pics of both sides, and full coin pics too 3 - If you can, use a box or something to put the cellphone on and point the camera lens Directly DOWN to the coin (not at an angle). 4 - Make sure the cell phone if FAR Enough AWAY from the coin so that it can focus on it. And make sure it does focus on the coin rather than the background. If the cell phone is to close the images will be fuzzy. 5 - make sure you crop the image (get rid of the dead space) before posting it. 6 - don't be in a hurry. It usually requires you to redo images .. we'll probably ask to redo images that we cannot see details of. So might as well do it right the first time and take your time. If you cannot see details in the images, neither can we. Also try to put dark coins (copper, etc) on a white surface (even plain white paper) and bright coins (clad, nickel, silver, etc) on a black surface (like black paper).
