Marnie's Morpeko #206 from Scarlet & Violet Promos is a reverse holo promo card that currently sells for about $29.00 ungraded, with graded copies ranging from $40.50 at grade 9 to $169 at grade 10. A grade 10 copy sells for around $169, about 5.8× the $29.00 raw price, so high-grade copies are worth grading.
