Guzma #SV84 from Hidden Fates Shiny Vault is a rare card that currently sells for about $20.20 ungraded, with graded copies ranging from $9.00 at grade 7 to $30.00 at grade 10. A grade 10 copy sells for around $30.00 vs $20.20 raw. That's a modest premium, so grading only pays off for near-perfect copies.
