A figure has rotational symmetry when it can rotate onto itself in less than a full rotation.
Depending on the font, they are N, S and Z.
The only state that has this type of symmetry when written horizontally is OHIO. If the letters are written vertically, then HAWAII, IOWA and UTAH also have symmetry.
OHIO possibly?
There is only one capital letter: O.
