Altaria #XY46 from XY Black Star Promos is a reverse holo promo card that currently sells for about $54.61 ungraded, with graded copies ranging from $33.00 at grade 7 to $71.00 at grade 9.5. A grade 9.5 copy sells for around $71.00 vs $54.61 raw. That's a modest premium, so grading only pays off for near-perfect copies.
