Rayquaza δ #16 from Holon Phantoms is a reverse holo holo_rare card that currently sells for about $65.50 ungraded, with graded copies ranging from $126 at grade 7 to $3,289 at grade 10. A grade 10 copy sells for around $3,289, about 50× the $65.50 raw price, so high-grade copies are worth grading.
