Pheromosa-GX #SM66 from SM Black Star Promos is a reverse holo promo card that currently sells for about $9.26 ungraded, with graded copies ranging from $40.70 at grade 9 to $115 at grade 10. A grade 10 copy sells for around $115, about 12× the $9.26 raw price, so high-grade copies are worth grading.
