Irida #GG63 from Crown Zenith Galarian Gallery is a rare card that currently sells for about $8.50 ungraded, with graded copies ranging from $7.50 at grade 7 to $15.00 at grade 10. A grade 10 copy sells for around $15.00 vs $8.50 raw. That's a modest premium, so grading only pays off for near-perfect copies.
