You are purchasing a full roll, 50 coins, all thirties Lincoln wheat cents, all "S" mints. This roll contains every date "S" mint to the thirties decade except 1931-S. As you know, there were no "S" mints 1932-1934. So this roll contains a nice assortment of the following dates: 1930-S, 1935-S, 1936-S, 1937-S, 1938-S, 1939-S. I have also done my best to remove culls.
The photo shows a typical roll.
