Great Tusk ex #72 from Scarlet & Violet Black Star Promos is a reverse holo promo card that currently sells for about $1.46 ungraded, with graded copies ranging from $0.99 at grade 7 to $20.50 at grade 10. A grade 10 copy sells for around $20.50, about 14× the $1.46 raw price, so high-grade copies are worth grading.
