What does everyone think? Found it in circulation. Comparison photos come directly from the Lincoln Cent Resource. 1946 there were three different mintmark styles used by the San Francisco mint. These styles are the Sans Serif, Serif, and Ball Serif. The Ball Serif is scarcer than the other two styles. This die variety is a 1946 S Lincoln Cent with an inverted mintmark. The mintmark was actually struck upside down. This is the only known inverted mintmark in the Lincoln series, and it can only be seen on the Ball Serif style 1946 S cents. This variety is extremely rare. It is recognized by Coneca and Wexler. ANACS will certify this variety. Images courtesy of BJ Neff
Look at the top of the MM. as you can see, it is very thin, now compare it to the two pictures. I believe the normal, non-inverted MM
