Bulbasaur #46 from Scarlet & Violet Black Star Promos is a reverse holo promo card that currently sells for about $1.64 ungraded, with graded copies ranging from $4.50 at grade 7 to $59.00 at grade 10. A grade 10 copy sells for around $59.00, about 36× the $1.64 raw price, so high-grade copies are worth grading.
