Quaxly #3 from Scarlet & Violet Black Star Promos is a reverse holo promo card that currently sells for about $0.99 ungraded, with graded copies ranging from $13.00 at grade 9 to $70.00 at grade 10. A grade 10 copy sells for around $70.00, about 71× the $0.99 raw price, so high-grade copies are worth grading.
