Garchomp ex #245 from Paradox Rift is a holo illustration_rare card that currently sells for about $33.75 ungraded, with graded copies ranging from $28.86 at grade 7 to $35.00 at grade 10. A grade 10 copy sells for around $35.00 vs $33.75 raw. That's a modest premium, so grading only pays off for near-perfect copies.
