Buzzwole #SM218 from SM Black Star Promos is a reverse holo promo card that currently sells for about $5.49 ungraded, with graded copies ranging from $24.15 at grade 9 to $61.70 at grade 10. A grade 10 copy sells for around $61.70, about 11× the $5.49 raw price, so high-grade copies are worth grading.
