Sword of Feast and Famine #296 from Double Masters is a mythic card that currently sells for about $110 ungraded, with graded copies ranging from $51.00 at grade 7 to $79.00 at grade 9.5. A grade 9.5 copy sells for around $79.00 vs $110 raw. That's a modest premium, so grading only pays off for near-perfect copies.
