Zacian ex #198 from Scarlet & Violet Promos is a reverse holo promo card that currently sells for about $1.99 ungraded, with graded copies ranging from $8.50 at grade 9 to $9.00 at grade 9.5. A grade 9.5 copy sells for around $9.00, about 4.5× the $1.99 raw price, so high-grade copies are worth grading.
