Flutter Mane #97 from Scarlet & Violet Black Star Promos is a reverse holo promo card that currently sells for about $3.78 ungraded, with graded copies ranging from $18.35 at grade 7 to $49.00 at grade 10. A grade 10 copy sells for around $49.00, about 13× the $3.78 raw price, so high-grade copies are worth grading.
