Sabrina's Alakazam #16 from Gym Challenge is a 1st edition holo holo_rare card that currently sells for about $232 ungraded, with graded copies ranging from $302 at grade 7 to $7,188 at grade 10. A grade 10 copy sells for around $7,188, about 31× the $232 raw price, so high-grade copies are worth grading.
