Giratina LV.X #DP38 from DP Black Star Promos is a reverse holo promo card that currently sells for about $30.75 ungraded, with graded copies ranging from $67.38 at grade 7 to $660 at grade 10. A grade 10 copy sells for around $660, about 21× the $30.75 raw price, so high-grade copies are worth grading.
