Grass Energy #103 from Power Keepers is a reverse holo holo_rare card that currently sells for about $4.18 ungraded, with graded copies ranging from $7.00 at grade 7 to $48.00 at grade 10. A grade 10 copy sells for around $48.00, about 12× the $4.18 raw price, so high-grade copies are worth grading.
