I found this dime and noticed something on the obverse side of the coin behind the crown of Roosevelt's head to me it appears to be a reversed letter D any help with this coin would be greatly appreciated thank you
I don’t see it, but a misplaced mint mark is ENTIRELY IMPOSSIBLE in 1990 coin. whatever you see i damage and worthless. Buy yourself some bazooka bubble gum
I so love error coins that they get more attention than my HUGE hoard of silver. Looking over this dime, I can’t see anything more than normal wear
