Eevee-GX #SM176 from SM Black Star Promos is a reverse holo promo card that currently sells for about $20.50 ungraded, with graded copies ranging from $21.50 at grade 9 to $133 at grade 10. A grade 10 copy sells for around $133, about 6.5× the $20.50 raw price, so high-grade copies are worth grading.
