Quote: I'm not seeing the any wear like the above comments
obv strike looks a little weak. small mark in front of nose rim tick at K4
rev a minor mark in the field to the left of ONE and some minor marks across some of the letters
i think this is not one of your better coins for assessment. maybe MS64+ or 65BN. I'm betting the coin may look better in hand
A nice red 1931-d is out of my price range , I am hoping this is original and I can get a 63 brown. If that's the case then I will come out better submitting then buying one. I think it's original but I am usually way off on these things It does have some marks and I would be thrilled if it came back 64 and not detailed. I took actual pictures instead of a scope hoping more experienced members would weigh in.
I heavily searched for a good 10 years to find a decent 31-D. Finding one in MS red in the raw is almost impossible. This is the best coin I could find, found it at a coin show. If you compare your coin to it, you can see why I'm leaning toward AU for yours.
taking a closer look at the surfaces on this one there could be some very slight wear on ends of the left wheat stock and on the second obv photos maybe some right above the eye on the forehead but the jacket is soooo clean from marks. these area also could be strike.
i can see at AU58 or MS63BN. maybe an angle shot of the obv would help but I'm still leaning to the MS side
