Imperial Recruiter #131 from Double Masters is a foil mythic card that currently sells for about $15.56 ungraded, with graded copies ranging from $23.55 at grade 9 to $26.00 at grade 9.5. A grade 9.5 copy sells for around $26.00 vs $15.56 raw. That's a modest premium, so grading only pays off for near-perfect copies.
