Inverted "S"

[AstroRaider]

I know, I know, I know... the only inverted "S" is with the 1946 wheat cent.

This 1945 is pretty beat up, and maybe that's why it looks like the mint mark is inverted.

Hey Allan, you coin does have the Ball serif mint mark however it's orientation is normal. The ball is on top as it should be in its normal position.
