Iono's Wattrel #231 from Ascended Heroes is a illustration_rare card that currently sells for about $8.09 ungraded, with graded copies ranging from $13.00 at grade 7 to $65.00 at grade 10. A grade 10 copy sells for around $65.00, about 8× the $8.09 raw price, so high-grade copies are worth grading.
