Manifold Key #398 from Time Spiral Remastered is a retro frame foil secret_rare card that currently sells for about $189 ungraded, with graded copies ranging from $98.00 at grade 9 to $108 at grade 9.5. A grade 9.5 copy sells for around $108 vs $189 raw. That's a modest premium, so grading only pays off for near-perfect copies.
