Paldean Wooper #41 from Scarlet & Violet Black Star Promos is a reverse holo promo card that currently sells for about $2.09 ungraded, with graded copies ranging from $12.65 at grade 9 to $49.99 at grade 10. A grade 10 copy sells for around $49.99, about 24× the $2.09 raw price, so high-grade copies are worth grading.
