Misty's Wish #108 from Gym Challenge is a 1st edition holo rare card that currently sells for about $14.99 ungraded, with graded copies ranging from $16.00 at grade 7 to $29.99 at grade 10. A grade 10 copy sells for around $29.99, about 2× the $14.99 raw price, so high-grade copies are worth grading.
