The 1928 Small S and Large S
Mintmarks have changed design many times during the Lincoln Cent Series. The most notable business strike mintmark
changes occurred in 1928 and 1941. The most notable proof mintmark changes occurred in 1979 and 1981. All of
these were S mintmark changes.
The 1928 Large S has more defined serifs than the small S. The middle of the mintmark in the 1928 Large S is much
thicker that the top and bottom.
This variety is listed in the Cherrypicker's Guide as FS 1-013.6 or FS-01-1928S-501. It is also listed in the Red
Book.
Of the population of 17,266,000 1928 S cents made, it is estimated that between 2%-5% are Large S.
