Charmander #47 from Scarlet & Violet Black Star Promos is a reverse holo promo card that currently sells for about $3.08 ungraded, with graded copies ranging from $7.00 at grade 7 to $60.00 at grade 10. A grade 10 copy sells for around $60.00, about 20× the $3.08 raw price, so high-grade copies are worth grading.
