Duraludon #69 from Prismatic Evolutions is a reverse holo common card that currently sells for about $0.10 ungraded, with graded copies ranging from $7.90 at grade 9 to $33.00 at grade 10. A grade 10 copy sells for around $33.00, about 330× the $0.10 raw price, so high-grade copies are worth grading.
