Sabrina's Alakazam #16 from Gym Challenge is a 1st edition holo holo_rare card that currently sells for about $282 ungraded, with graded copies ranging from $307 at grade 7 to $8,089 at grade 10. A grade 10 copy sells for around $8,089, about 29× the $282 raw price, so high-grade copies are worth grading.
