Articuno #48 from Wizards Black Star Promos is a promo card that currently sells for about $52.00 ungraded, with graded copies ranging from $29.00 at grade 7 to $89.99 at grade 10. A grade 10 copy sells for around $89.99 vs $52.00 raw. That's a modest premium, so grading only pays off for near-perfect copies.
