Mega Heracross ex #4 from Phantasmal Flames is a reverse holo rare card that currently sells for about $1.17 ungraded, with graded copies ranging from $12.13 at grade 9 to $32.00 at grade 10. A grade 10 copy sells for around $32.00, about 27× the $1.17 raw price, so high-grade copies are worth grading.
