Lucario LV.X #DP12 from DP Black Star Promos is a reverse holo promo card that currently sells for about $29.99 ungraded, with graded copies ranging from $60.00 at grade 7 to $630 at grade 10. A grade 10 copy sells for around $630, about 21× the $29.99 raw price, so high-grade copies are worth grading.
