Team Magma's Groudon #9 from Celebrations: Classic Collection is a reverse holo common card that currently sells for about $2.58 ungraded, with graded copies ranging from $11.99 at grade 7 to $66.00 at grade 10. A grade 10 copy sells for around $66.00, about 26× the $2.58 raw price, so high-grade copies are worth grading.
