Walking Wake ex #215 from Temporal Forces is a holo hyper_rare card that currently sells for about $9.25 ungraded, with graded copies ranging from $22.00 at grade 9 to $44.99 at grade 10. A grade 10 copy sells for around $44.99, about 4.9× the $9.25 raw price, so high-grade copies are worth grading.
