Lt. Surge's Jolteon #28 from Gym Challenge is a 1st edition holo rare card that currently sells for about $24.02 ungraded, with graded copies ranging from $15.00 at grade 7 to $300 at grade 10. A grade 10 copy sells for around $300, about 13× the $24.02 raw price, so high-grade copies are worth grading.
