That quarter is pretty worn. Even a seasoned collector could have a hard time attributing it. There's just not enough detail in your photos to help.
Is there a website that you referenced your quarter from? How did you determine it was DD ? It's heavily worn which really flattens everything.
This is what you have to do OP . Since Coneca doesn't have any images showing, you have to use their quick chart . http://varietyvista.com/Variety Master Listings/washington doubled dies 1942.htm#_1942-D Try to match the markers that Coneca has listed for their DDOs for that year & mint-mark . Take some images of any markers you can find . Then I can help ..
You can go here-http://doubleddie.com/1697074.html to find an image. The only worthwhile obv d die for the date/Mint is 1-O-I/DDO-001 and your coin isn't that one.
