Jin-Gitaxias // The Great Synthesis #339 from March of the Machine is a full art foil / borderless mythic card that currently sells for about $920 ungraded, with graded copies ranging from $2,244 at grade 9 to $1,137 at grade 9.5. A grade 9.5 copy sells for around $1,137 vs $920 raw. That's a modest premium, so grading only pays off for near-perfect copies.
