the chance of a 68 is pretty much zero. grading any coin by photo above a 66 is crap shoot. every tiny little detail comes into play.
based on your photos the rev looks 67 maybe a +. however the obv photo is not enough to assess it properly. the photo shows missing luster or possibly cabinet rub at the top of the head above the ear as well as some on the high point of the cheek and the bridge of the nose. is that there? cant tell for sure as lighting/glare can skew that. the field to left of the profile appears to be missing luster also or some type of scuffing or rub. I think you have an MS67 coin. which is quite nice
i order to cover the cost of grading the coin would need to be 67+ or 68
