Metagross-EX #XY34 from XY Black Star Promos is a reverse holo promo card that currently sells for about $14.04 ungraded, with graded copies ranging from $25.00 at grade 7 to $155 at grade 10. A grade 10 copy sells for around $155, about 11× the $14.04 raw price, so high-grade copies are worth grading.
