Erika's Ivysaur #41 from Gym Challenge is a 1st edition uncommon card that currently sells for about $19.99 ungraded, with graded copies ranging from $12.51 at grade 7 to $300 at grade 10. A grade 10 copy sells for around $300, about 15× the $19.99 raw price, so high-grade copies are worth grading.
