Kangaskhan #SWSH038 from SWSH Black Star Promos is a reverse holo promo card that currently sells for about $11.00 ungraded, with graded copies ranging from $29.99 at grade 9 to $50.00 at grade 10. A grade 10 copy sells for around $50.00, about 4.5× the $11.00 raw price, so high-grade copies are worth grading.
