Dark Slowking #9 from Team Rocket Returns is a holo holo_rare card that currently sells for about $80.00 ungraded, with graded copies ranging from $91.00 at grade 7 to $2,800 at grade 10. A grade 10 copy sells for around $2,800, about 35× the $80.00 raw price, so high-grade copies are worth grading.
