Zapdos #SM159 from SM Black Star Promos is a reverse holo promo card that currently sells for about $19.50 ungraded, with graded copies ranging from $20.31 at grade 7 to $165 at grade 10. A grade 10 copy sells for around $165, about 8.5× the $19.50 raw price, so high-grade copies are worth grading.
