Stufful #154 from Mega Evolution is a reverse holo illustration_rare card that currently sells for about $6.13 ungraded, with graded copies ranging from $7.50 at grade 7 to $30.00 at grade 10. A grade 10 copy sells for around $30.00, about 4.9× the $6.13 raw price, so high-grade copies are worth grading.
