Shining Celebi #SM79 from SM Black Star Promos is a reverse holo promo card that currently sells for about $25.09 ungraded, with graded copies ranging from $18.00 at grade 7 to $575 at grade 10. A grade 10 copy sells for around $575, about 23× the $25.09 raw price, so high-grade copies are worth grading.
