Ulamog, the Infinite Gyre #3 from Double Masters 2022 is a mythic card that currently sells for about $91.32 ungraded, with graded copies ranging from $140 at grade 9 to $150 at grade 10. A grade 10 copy sells for around $150 vs $91.32 raw. That's a modest premium, so grading only pays off for near-perfect copies.
