I hit another private lot the other day & came home with six wheat pennys the oldest was the best. When I saw the 1922 I looked for a mint mark & could not see one, when I got home I rinsed off the coin & only when I put it under a glass could I see the d. I did not want it to be there but I guess it is better than nothing, I would guess it might go f12 so a $55 coin instead of a $1200 coin. I would take a pic but the 22'S are so weak any way my camera can't catch the detail.
