the hits on the cheek are not bad enough to drop the grade imo. I agree with subdued luster however could be from lighting or holder. always remove coin from holder when possible as it alters the look of the coin. in this case it really doesn't matter that much regarding value as there is only a few dollars difference in grade.
AU58 or MS62. the fingerprint at K5 reverse wont affect that. i'll say MS62 without better photos
