Erika's Kindness #103 from Gym Challenge is a 1st edition holo rare card that currently sells for about $17.50 ungraded, with graded copies ranging from $4.41 at grade 7 to $14.99 at grade 10. A grade 10 copy sells for around $14.99 vs $17.50 raw. That's a modest premium, so grading only pays off for near-perfect copies.
