I know next to nothing about coin grading but I'll guess MS60 because of some rubbing above the eye, on the cheek, and maybe on the shoulder, and the marks/scratches previously mentioned by others.
It is the color designation for Red. So on the slab it will have the grade MS-64 RD. Or RB for Red brown or BN for brown.
In terms of value red is the most valuable then red brown then brown. However I find high grade brown examples more attractive than red, just personal preference really.
