Zapdos ex #49 from Scarlet & Violet Black Star Promos is a reverse holo promo card that currently sells for about $1.53 ungraded, with graded copies ranging from $11.73 at grade 9 to $70.00 at grade 10. A grade 10 copy sells for around $70.00, about 46× the $1.53 raw price, so high-grade copies are worth grading.
