Snapcaster Mage #478 from Innistrad Remastered is a retro frame mythic card that currently sells for about $20.73 ungraded, with graded copies ranging from $25.99 at grade 9 to $29.99 at grade 10. A grade 10 copy sells for around $29.99 vs $20.73 raw. That's a modest premium, so grading only pays off for near-perfect copies.
