Krookodile #66 from Dark Explorers is a reverse holo holo_rare card that currently sells for about $1.97 ungraded, with graded copies ranging from $40.00 at grade 9 to $59.40 at grade 10. A grade 10 copy sells for around $59.40, about 30× the $1.97 raw price, so high-grade copies are worth grading.
