Growlithe #24 from Scarlet & Violet Black Star Promos is a reverse holo promo card that currently sells for about $1.40 ungraded, with graded copies ranging from $7.75 at grade 7 to $90.00 at grade 10. A grade 10 copy sells for around $90.00, about 64× the $1.40 raw price, so high-grade copies are worth grading.
