Rayquaza V #193 from Evolving Skies is a holo rare card that currently sells for about $72.50 ungraded, with graded copies ranging from $13.55 at grade 7 to $26.00 at grade 10. A grade 10 copy sells for around $26.00 vs $72.50 raw. That's a modest premium, so grading only pays off for near-perfect copies.
