Hoopa-EX #XY85 from XY Black Star Promos is a reverse holo promo card that currently sells for about $12.15 ungraded, with graded copies ranging from $12.50 at grade 7 to $128 at grade 10. A grade 10 copy sells for around $128, about 11× the $12.15 raw price, so high-grade copies are worth grading.
