Butterfree V #1 from Darkness Ablaze is a holo holo_rare card that currently sells for about $1.42 ungraded, with graded copies ranging from $5.50 at grade 7 to $0.99 at grade 10. A grade 10 copy sells for around $0.99 vs $1.42 raw. That's a modest premium, so grading only pays off for near-perfect copies.
