Sinistea #62 from Scarlet & Violet Black Star Promos is a reverse holo promo card that currently sells for about $1.50 ungraded, with graded copies ranging from $10.00 at grade 9 to $68.54 at grade 10. A grade 10 copy sells for around $68.54, about 46× the $1.50 raw price, so high-grade copies are worth grading.
