Ba Sing Se #266 from Avatar: The Last Airbender is a rare card that currently sells for about $22.48 ungraded, with graded copies ranging from $26.00 at grade 9 to $29.00 at grade 9.5. A grade 9.5 copy sells for around $29.00 vs $22.48 raw. That's a modest premium, so grading only pays off for near-perfect copies.
