Serperior VSTAR #196 from Silver Tempest is a rare card that currently sells for about $5.89 ungraded, with graded copies ranging from $18.99 at grade 9 to $7.50 at grade 10. A grade 10 copy sells for around $7.50 vs $5.89 raw. That's a modest premium, so grading only pays off for near-perfect copies.
