Hariyama ex #100 from Deoxys is a holo holo_rare card that currently sells for about $35.89 ungraded, with graded copies ranging from $41.49 at grade 7 to $59.99 at grade 10. A grade 10 copy sells for around $59.99 vs $35.89 raw. That's a modest premium, so grading only pays off for near-perfect copies.
