Yawgmoth, Thran Physician #110 from Dominaria Remastered is a foil mythic card that currently sells for about $31.95 ungraded, with graded copies ranging from $31.94 at grade 7 to $39.99 at grade 10. A grade 10 copy sells for around $39.99 vs $31.95 raw. That's a modest premium, so grading only pays off for near-perfect copies.
