I don't think so. I think the toning is obscuring some of the luster. It could go either way, as the coin is a slider, but I would go with MS on this one.
Look at the areas around the stars, in front and behind the bust, and above the eagle. You can see a halo effect caused by the wearing away of luster.
Technical grade of 58 due to rub, market graded to 61/62 for eye appeal as it has decent looking surfaces.
