Alolan Diglett #9 from McDonald's Collection 2017 is a reverse holo common card that currently sells for about $2.99 ungraded, with graded copies ranging from $19.02 at grade 7 to $45.22 at grade 10. A grade 10 copy sells for around $45.22, about 15× the $2.99 raw price, so high-grade copies are worth grading.
