Mega Gengar ex #269 from Ascended Heroes is a reverse holo ultra_rare card that currently sells for about $62.55 ungraded, with graded copies ranging from $59.00 at grade 7 to $280 at grade 10. A grade 10 copy sells for around $280, about 4.5× the $62.55 raw price, so high-grade copies are worth grading.
