Litten #15 from McDonald's Collection 2021 is a reverse holo common card that currently sells for about $2.56 ungraded, with graded copies ranging from $7.00 at grade 7 to $50.00 at grade 10. A grade 10 copy sells for around $50.00, about 20× the $2.56 raw price, so high-grade copies are worth grading.
