Blastoise ex #200 from 151 is a reverse holo illustration_rare card that currently sells for about $76.00 ungraded, with graded copies ranging from $58.25 at grade 7 to $90.00 at grade 10. A grade 10 copy sells for around $90.00 vs $76.00 raw. That's a modest premium, so grading only pays off for near-perfect copies.
