Aegis of the Gods #1 from Journey into Nyx is a rare card that currently sells for about $4.57 ungraded, with graded copies ranging from $6.21 at grade 7 to $5.00 at grade 9.5. A grade 9.5 copy sells for around $5.00 vs $4.57 raw. That's a modest premium, so grading only pays off for near-perfect copies.
