Mega Heracross ex #108 from Phantasmal Flames is a holo ultra_rare card that currently sells for about $2.49 ungraded, with graded copies ranging from $13.31 at grade 7 to $44.50 at grade 10. A grade 10 copy sells for around $44.50, about 18× the $2.49 raw price, so high-grade copies are worth grading.
