Victini #XY117 from XY Black Star Promos is a reverse holo promo card that currently sells for about $32.50 ungraded, with graded copies ranging from $46.00 at grade 7 to $4,550 at grade 10. A grade 10 copy sells for around $4,550, about 140× the $32.50 raw price, so high-grade copies are worth grading.
