Mr. Mime-GX #56 from Celestial Storm is a reverse holo holo_rare card that currently sells for about $4.46 ungraded, with graded copies ranging from $14.00 at grade 7 to $58.00 at grade 10. A grade 10 copy sells for around $58.00, about 13× the $4.46 raw price, so high-grade copies are worth grading.
