I'll give you my quick opinion -
1955D - PMD maybe environmental damage/corrosion
1939 - Maybe a lamination error on the right side of the coin with some PMD at places on the rim
1945 - looks like some staining, perhaps from sitting on an only cloth
1953 - PMD, road rash on reverse design maybe indicates a parking lot coin at some point in it's life.
The only possible error coin I see is the 1939 if it is indeed a lamination error. Let's wait for some of the local experts to ring in.
