BBBeth, did you look at Wexlers? the fours look to me like the fours in the 1944 D WDDO 3 Stage A. The other photos aren't clear enough for my eyes to see any of the other markers. Hope this helps.
Check it against these. That is no doubt a DDO http://varietyvista.com/01a LC Doubled Dies Vol 1/DDO 1944-D.htm
I have no doubt that the 1944-DDO1 in the VV list is a DDO, notice the bottom of the 4s. But ( apologies) I think the rest of VV listing are very doubtful and valueless IMO. Jim
I was lucky. Looked at two 1944-Ds consecutively and saw a difference. Probably should sort all my Lincolns by date. Now I'm thinking should I go through all my pennies again. Ouch!
