Balefire Dragon #479 from Innistrad Remastered is a retro frame foil mythic card that currently sells for about $15.55 ungraded, with graded copies ranging from $26.99 at grade 9 to $16.51 at grade 10. A grade 10 copy sells for around $16.51 vs $15.55 raw. That's a modest premium, so grading only pays off for near-perfect copies.
