There's not a whole lot to say. Millions were minted during the war, primarily out of expended shell casings. They're worth about 3-4 cents a piece. There is a nice 1944 D/S variety out there that is worth money.
I can tell you it's the D over S mint mark not the S over D. If one of those 3 in your opening post's photo is what you think is an D/S, the pics are too small to tell. Any chance you can get a close up of the date and mint mark?
This is what to look for: OMM 1 the more desirable and valuable. OMM 2 Here's the link to the source http://www.lincolncentresource.com/OMMS/1944omm1and2.html
