Raichu-GX #SM90 from SM Black Star Promos is a reverse holo promo card that currently sells for about $9.36 ungraded, with graded copies ranging from $13.50 at grade 7 to $69.00 at grade 10. A grade 10 copy sells for around $69.00, about 7.4× the $9.36 raw price, so high-grade copies are worth grading.
