Ampharos ex #16 from Scarlet & Violet Black Star Promos is a reverse holo promo card that currently sells for about $5.27 ungraded, with graded copies ranging from $5.50 at grade 7 to $44.95 at grade 10. A grade 10 copy sells for around $44.95, about 8.5× the $5.27 raw price, so high-grade copies are worth grading.
