Pikachu V-UNION #SWSH141 from SWSH Black Star Promos is a reverse holo promo card that currently sells for about $7.15 ungraded, with graded copies ranging from $20.00 at grade 7 to $105 at grade 10. A grade 10 copy sells for around $105, about 15× the $7.15 raw price, so high-grade copies are worth grading.
