Griselbrand #115 from Innistrad Remastered is a mythic card that currently sells for about $18.47 ungraded, with graded copies ranging from $31.05 at grade 9 to $25.00 at grade 10. A grade 10 copy sells for around $25.00 vs $18.47 raw. That's a modest premium, so grading only pays off for near-perfect copies.
