Vulpix #138 from Mega Evolution is a reverse holo illustration_rare card that currently sells for about $17.00 ungraded, with graded copies ranging from $11.00 at grade 7 to $90.00 at grade 10. A grade 10 copy sells for around $90.00, about 5.3× the $17.00 raw price, so high-grade copies are worth grading.
