Cosmog #6 from McDonald's Collection 2017 is a reverse holo common card that currently sells for about $2.08 ungraded, with graded copies ranging from $16.27 at grade 9 to $40.58 at grade 10. A grade 10 copy sells for around $40.58, about 20× the $2.08 raw price, so high-grade copies are worth grading.
