Darkrai-GX #SV70 from Hidden Fates Shiny Vault is a shiny card that currently sells for about $50.00 ungraded, with graded copies ranging from $20.00 at grade 7 to $69.95 at grade 10. A grade 10 copy sells for around $69.95 vs $50.00 raw. That's a modest premium, so grading only pays off for near-perfect copies.
