Rocket's Hitmonchan #11 from Gym Heroes is a unlimited holo holo_rare card that currently sells for about $8.00 ungraded, with graded copies ranging from $29.99 at grade 7 to $1,999 at grade 10. A grade 10 copy sells for around $1,999, about 250× the $8.00 raw price, so high-grade copies are worth grading.
