Phyrexian Altar #396 from Double Masters 2022 is a full art / borderless rare card that currently sells for about $51.94 ungraded, with graded copies ranging from $49.15 at grade 7 to $48.00 at grade 10. A grade 10 copy sells for around $48.00 vs $51.94 raw. That's a modest premium, so grading only pays off for near-perfect copies.
