Erika's Dragonair #4 from Gym Heroes is a 1st edition holo holo_rare card that currently sells for about $151 ungraded, with graded copies ranging from $120 at grade 7 to $2,400 at grade 10. A grade 10 copy sells for around $2,400, about 16× the $151 raw price, so high-grade copies are worth grading.
