Yes they are. Unfortunately , your coin is not a 1971-D DDR-001 (FS-801). http://varietyvista.com/09b WQ Vol 2/DDR Detail Pages/1971DDDR001.htm
I do not have my microscope it's in my storage unit buried so I'm just using my cell phone to take pictures of it
Yes, I’ve looked at all your pictures. Unfortunately this is not a doubled die. Your coin has circulation damage, die wear, and what I can see from your pictures die deterioration doubling. Sorry
This is For The guy that said my 1971 d quarter was not a Doubled die I finally got my microscope and check it out worthless doubling huh
Nope.. You're still wrong. That's machine doubling. Not a Doubled Die Thanks for the magnified areas. It shows that it is definitely worthless doubling.
what you have is machine doubling very common on many coins not any sort of major error or worth anything
