Kyogre ex #178 from Scarlet & Violet Promos is a reverse holo promo card that currently sells for about $2.53 ungraded, with graded copies ranging from $25.00 at grade 9 to $355 at grade 10. A grade 10 copy sells for around $355, about 140× the $2.53 raw price, so high-grade copies are worth grading.
