Pikachu #6 from McDonald's Collection 2019 is a reverse holo common card that currently sells for about $2.79 ungraded, with graded copies ranging from $10.50 at grade 7 to $69.00 at grade 10. A grade 10 copy sells for around $69.00, about 25× the $2.79 raw price, so high-grade copies are worth grading.
