Watery Grave #286 from Edge of Eternities is a showcase foil / borderless rare card that currently sells for about $31.99 ungraded, with graded copies ranging from $29.95 at grade 9 to $33.00 at grade 9.5. A grade 9.5 copy sells for around $33.00 vs $31.99 raw. That's a modest premium, so grading only pays off for near-perfect copies.
