Hop's Trevenant #237 from Ascended Heroes is a illustration_rare card that currently sells for about $5.30 ungraded, with graded copies ranging from $22.01 at grade 9 to $82.00 at grade 10. A grade 10 copy sells for around $82.00, about 16× the $5.30 raw price, so high-grade copies are worth grading.
