Basic Metal Energy #99 from Shrouded Fable is a holo hyper_rare card that currently sells for about $25.95 ungraded, with graded copies ranging from $29.52 at grade 9 to $26.00 at grade 10. A grade 10 copy sells for around $26.00 vs $25.95 raw. That's a modest premium, so grading only pays off for near-perfect copies.
