Yawgmoth, Thran Physician #116 from Modern Horizons is a mythic card that currently sells for about $30.95 ungraded, with graded copies ranging from $1.06 at grade 7 to $33.00 at grade 9.5. A grade 9.5 copy sells for around $33.00 vs $30.95 raw. That's a modest premium, so grading only pays off for near-perfect copies.
