Sabrina's Alakazam #16 from Gym Challenge is a 1st edition holo holo_rare card that currently sells for about $227 ungraded, with graded copies ranging from $299 at grade 7 to $5,425 at grade 10. A grade 10 copy sells for around $5,425, about 24× the $227 raw price, so high-grade copies are worth grading.
