By the way, the 1946S ball serif mintmark style represents the lowest known percentage of strikes of any mintmark style variety in Lincoln cents. The 1928S large mintmark represents roughly 20% of all surviving 1928S cents, and the 1941S large S and small S mintmarks are realistically nearly even in number.
Other years that exhibit differing mintmark styles are 1944S, 1945S, 1947S, 1948S(?), 1952D, 1979S, and 1981S. I put a question mark on the 1948S because there are reports of a second mintmark style existing that year, but to date I have never seen confirmation nor an example in image or in hand. The only confirmed style of mintmark for 1948S is the serif style like the one in Morgansrmine's photograph.
