Magikarp & Wailord-GX #160 from Team Up is a holo rare card that currently sells for about $89.95 ungraded, with graded copies ranging from $64.00 at grade 7 to $99.99 at grade 10. A grade 10 copy sells for around $99.99 vs $89.95 raw. That's a modest premium, so grading only pays off for near-perfect copies.
