Flapple #SWSH022 from SWSH Black Star Promos is a reverse holo promo card that currently sells for about $7.39 ungraded, with graded copies ranging from $13.50 at grade 9 to $25.00 at grade 10. A grade 10 copy sells for around $25.00, about 3.4× the $7.39 raw price, so high-grade copies are worth grading.
