Charmander #SWSH092 from SWSH Black Star Promos is a reverse holo promo card that currently sells for about $5.87 ungraded, with graded copies ranging from $13.99 at grade 7 to $450 at grade 10. A grade 10 copy sells for around $450, about 77× the $5.87 raw price, so high-grade copies are worth grading.
