Walking Wake ex #178 from Prismatic Evolutions is a holo hyper_rare card that currently sells for about $7.19 ungraded, with graded copies ranging from $11.00 at grade 7 to $86.00 at grade 10. A grade 10 copy sells for around $86.00, about 12× the $7.19 raw price, so high-grade copies are worth grading.
