I have examined a 1993 (no D mintmark) Lincoln cent that has two distinct doubled columns, on the 5th column and on the 8th column. The doubled column on the 5th runs top to bottom, and the 8th column has a doubled column that runs from the top, about 3/4 of the way down, turning inward slightly and blending back in to the background at the base. The doubled columns are visible in several varieties on 1993-D cents, according to Wexler, which include variant WDDR-011, WDDR-012, WDDR-013, and WDDR-014. This one, however, is not catalogued, and it appears more pronounced than the four known varieties.
