Iron Leaves ex #128 from Scarlet & Violet Black Star Promos is a reverse holo promo card that currently sells for about $1.55 ungraded, with graded copies ranging from $9.09 at grade 9 to $16.00 at grade 10. A grade 10 copy sells for around $16.00, about 10× the $1.55 raw price, so high-grade copies are worth grading.
