Scream Tail #65 from Scarlet & Violet Black Star Promos is a reverse holo promo card that currently sells for about $6.49 ungraded, with graded copies ranging from $9.50 at grade 7 to $75.00 at grade 10. A grade 10 copy sells for around $75.00, about 12× the $6.49 raw price, so high-grade copies are worth grading.
