Wailord ex #100 from Sandstorm is a reverse holo holo_rare card that currently sells for about $72.55 ungraded, with graded copies ranging from $75.00 at grade 7 to $94.99 at grade 10. A grade 10 copy sells for around $94.99 vs $72.55 raw. That's a modest premium, so grading only pays off for near-perfect copies.
