I would like to gather some opinions on the grade of this here 1915 J 1/2 Mark. Overall the coin appears to be Au in my (extremely humble) opinion. But the details on the obverse screams Xf into my ear (quite loudly). I'm looking for a quasi-accurate grade so I can attribute it with an equally quasi-accurate value. (and so I can get a feel for what a "mint-state" coin of this type may actually look like.
