I have a 1940 nickel with possible errors. The 0 in 1940 has some dot on it. The D in God has a line over it. So is it wear and tear or an error? If it's an error, does it have any value? Thanks!
Looks sort of like PMD to me, only because of the amount of wear right there by the CUD-like area. Hard to say as to the 0, as it's pretty gunked up.
