Blissey ex #201 from Twilight Masquerade is a holo ultra_rare card that currently sells for about $4.71 ungraded, with graded copies ranging from $16.51 at grade 9 to $46.00 at grade 10. A grade 10 copy sells for around $46.00, about 9.8× the $4.71 raw price, so high-grade copies are worth grading.
