Ivysaur #134 from Mega Evolution is a holo illustration_rare card that currently sells for about $18.50 ungraded, with graded copies ranging from $19.99 at grade 7 to $77.00 at grade 10. A grade 10 copy sells for around $77.00, about 4.2× the $18.50 raw price, so high-grade copies are worth grading.
