Deflecting Palm #173 from Khans of Tarkir is a rare card that currently sells for about $9.50 ungraded, with graded copies ranging from $5.00 at grade 7 to $6.50 at grade 8. A grade 8 copy sells for around $6.50 vs $9.50 raw. That's a modest premium, so grading only pays off for near-perfect copies.
