Riolu #GG26 from Crown Zenith Galarian Gallery is a reverse holo holo_rare card that currently sells for about $10.96 ungraded, with graded copies ranging from $9.00 at grade 7 to $220 at grade 10. A grade 10 copy sells for around $220, about 20× the $10.96 raw price, so high-grade copies are worth grading.
