Iono's Wattrel #231 from Ascended Heroes is a holo illustration_rare card that currently sells for about $9.00 ungraded, with graded copies ranging from $9.23 at grade 7 to $49.89 at grade 10. A grade 10 copy sells for around $49.89, about 5.5× the $9.00 raw price, so high-grade copies are worth grading.
