Ash's Pikachu #SM113 from SM Black Star Promos is a reverse holo promo card that currently sells for about $32.26 ungraded, with graded copies ranging from $17.50 at grade 7 to $850 at grade 10. A grade 10 copy sells for around $850, about 26× the $32.26 raw price, so high-grade copies are worth grading.
