Tyrantrum-EX #XY70 from XY Black Star Promos is a reverse holo promo card that currently sells for about $9.00 ungraded, with graded copies ranging from $175 at grade 7 to $230 at grade 10. A grade 10 copy sells for around $230, about 26× the $9.00 raw price, so high-grade copies are worth grading.
