Sabrina's Alakazam #16 from Gym Challenge is a 1st edition holo holo_rare card that currently sells for about $224 ungraded, with graded copies ranging from $289 at grade 7 to $4,475 at grade 10. A grade 10 copy sells for around $4,475, about 20× the $224 raw price, so high-grade copies are worth grading.
