Sylveon-GX #SV76 from Hidden Fates Shiny Vault is a holo shiny card that currently sells for about $142 ungraded, with graded copies ranging from $40.54 at grade 7 to $155 at grade 10. A grade 10 copy sells for around $155 vs $142 raw. That's a modest premium, so grading only pays off for near-perfect copies.
