Rampardos ex #045 from Pitch Black is a holo rare card that currently sells for about $1.58 ungraded, with graded copies ranging from $11.70 at grade 9 to $1.25 at grade 10. A grade 10 copy sells for around $1.25 vs $1.58 raw. That's a modest premium, so grading only pays off for near-perfect copies.
