Tifa Lockhart #391 from Final Fantasy is a full art / borderless rare card that currently sells for about $1,925 ungraded, with graded copies ranging from $3,050 at grade 9 to $2,400 at grade 10. A grade 10 copy sells for around $2,400 vs $1,925 raw. That's a modest premium, so grading only pays off for near-perfect copies.
