Frosmoth #SWSH007 from SWSH Black Star Promos is a reverse holo promo card that currently sells for about $7.77 ungraded, with graded copies ranging from $15.72 at grade 9 to $120 at grade 10. A grade 10 copy sells for around $120, about 15× the $7.77 raw price, so high-grade copies are worth grading.
