Vampiric Tutor #108 from Dominaria Remastered is a foil mythic card that currently sells for about $60.74 ungraded, with graded copies ranging from $42.39 at grade 7 to $110 at grade 10. A grade 10 copy sells for around $110 vs $60.74 raw. That's a modest premium, so grading only pays off for near-perfect copies.
