Erika's Venusaur #4 from Gym Challenge is a unlimited holo holo_rare card that currently sells for about $11.41 ungraded, with graded copies ranging from $15.06 at grade 7 to $83.00 at grade 10. A grade 10 copy sells for around $83.00, about 7.3× the $11.41 raw price, so high-grade copies are worth grading.
