Glaceon #BW90 from BW Black Star Promos is a reverse holo promo card that currently sells for about $25.00 ungraded, with graded copies ranging from $32.74 at grade 7 to $3,000 at grade 10. A grade 10 copy sells for around $3,000, about 120× the $25.00 raw price, so high-grade copies are worth grading.
