Teal Mask Ogerpon ex #221 from Twilight Masquerade is a hyper_rare card that currently sells for about $8.38 ungraded, with graded copies ranging from $20.50 at grade 9 to $110 at grade 10. A grade 10 copy sells for around $110, about 13× the $8.38 raw price, so high-grade copies are worth grading.
