Gumshoos #153 from Mega Evolution is a reverse holo illustration_rare card that currently sells for about $4.00 ungraded, with graded copies ranging from $14.00 at grade 7 to $71.00 at grade 10. A grade 10 copy sells for around $71.00, about 18× the $4.00 raw price, so high-grade copies are worth grading.
