Mudkip ★ #107 from Team Rocket Returns is a holo holo_rare card that currently sells for about $2,223 ungraded, with graded copies ranging from $3,899 at grade 7 to $3,000 at grade 10. A grade 10 copy sells for around $3,000 vs $2,223 raw. That's a modest premium, so grading only pays off for near-perfect copies.
