Nidoqueen #SM160 from SM Black Star Promos is a reverse holo promo card that currently sells for about $21.91 ungraded, with graded copies ranging from $14.00 at grade 7 to $75.00 at grade 10. A grade 10 copy sells for around $75.00, about 3.4× the $21.91 raw price, so high-grade copies are worth grading.
