Marnie's Grimmsnarl ex #287 from Ascended Heroes is a holo illustration_rare card that currently sells for about $51.68 ungraded, with graded copies ranging from $50.28 at grade 7 to $106 at grade 10. A grade 10 copy sells for around $106, about 2× the $51.68 raw price, so high-grade copies are worth grading.
