Helioptile #143 from Mega Evolution is a holo illustration_rare card that currently sells for about $4.02 ungraded, with graded copies ranging from $7.50 at grade 7 to $25.00 at grade 10. A grade 10 copy sells for around $25.00, about 6.2× the $4.02 raw price, so high-grade copies are worth grading.
