In my opinion, treat it as a raw coin as it is not graded by either of the two most respected grading companies. I would put more focus on what the actual coin looks like than what the holder says. The reason I say this is because the asking price would be alot more concrete if graded by NGC or PCGS. Being that its not, I would be a little harder on your own personal grading skills, especially when delineating between two mint states, and this is especially key when they jump. At least thats what I do....
