Sliver Legion #261 from Time Spiral Remastered is a mythic card that currently sells for about $43.04 ungraded, with graded copies ranging from $44.99 at grade 9 to $49.00 at grade 9.5. A grade 9.5 copy sells for around $49.00 vs $43.04 raw. That's a modest premium, so grading only pays off for near-perfect copies.
