Fuecoco #2 from Scarlet & Violet Black Star Promos is a reverse holo promo card that currently sells for about $1.19 ungraded, with graded copies ranging from $11.67 at grade 9 to $25.00 at grade 10. A grade 10 copy sells for around $25.00, about 21× the $1.19 raw price, so high-grade copies are worth grading.
