Bloodchief Ascension #636 from Commander Masters is a full art foil / borderless rare card that currently sells for about $32.80 ungraded, with graded copies ranging from $30.00 at grade 9 to $33.00 at grade 9.5. A grade 9.5 copy sells for around $33.00 vs $32.80 raw. That's a modest premium, so grading only pays off for near-perfect copies.
