Onix #9 from McDonald's Collection 2019 is a reverse holo common card that currently sells for about $4.41 ungraded, with graded copies ranging from $44.95 at grade 9 to $48.40 at grade 10. A grade 10 copy sells for around $48.40, about 11× the $4.41 raw price, so high-grade copies are worth grading.
