Fennekin #14 from McDonald's Collection 2021 is a reverse holo common card that currently sells for about $1.10 ungraded, with graded copies ranging from $9.80 at grade 7 to $38.11 at grade 10. A grade 10 copy sells for around $38.11, about 35× the $1.10 raw price, so high-grade copies are worth grading.
