Cinderace ex #163 from Scarlet & Violet Black Star Promos is a reverse holo promo card that currently sells for about $6.00 ungraded, with graded copies ranging from $15.04 at grade 7 to $120 at grade 10. A grade 10 copy sells for around $120, about 20× the $6.00 raw price, so high-grade copies are worth grading.
