Team Rocket's Ariana #224 from Destined Rivals is a ultra_rare card that currently sells for about $4.79 ungraded, with graded copies ranging from $11.76 at grade 7 to $2.25 at grade 10. A grade 10 copy sells for around $2.25 vs $4.79 raw. That's a modest premium, so grading only pays off for near-perfect copies.
