Spidops #9 from Scarlet & Violet Black Star Promos is a reverse holo promo card that currently sells for about $1.81 ungraded, with graded copies ranging from $7.50 at grade 9 to $8.00 at grade 9.5. A grade 9.5 copy sells for around $8.00, about 4.4× the $1.81 raw price, so high-grade copies are worth grading.
