The Great Henge #294 from Commander Masters is a mythic card that currently sells for about $55.00 ungraded, with graded copies ranging from $47.62 at grade 9 to $52.00 at grade 9.5. A grade 9.5 copy sells for around $52.00 vs $55.00 raw. That's a modest premium, so grading only pays off for near-perfect copies.
