I have an extra 1939-S nickel that I got from a roll. Still a key date, but I already have that slot filled in my Whitman Folder. Maybe someone would trade? I only have 8 slots remaining in my folder (38-D, 39-D, 42-S, 43-D, 49-S, 51-S, 53-S, and 55). Anyone willing to trade my 1939-S for one on my list?
