Gardevoir-EX #78 from Steam Siege is a reverse holo holo_rare card that currently sells for about $4.10 ungraded, with graded copies ranging from $14.00 at grade 7 to $38.69 at grade 10. A grade 10 copy sells for around $38.69, about 9.4× the $4.10 raw price, so high-grade copies are worth grading.
