Professor Sada's Vitality #256 from Paradox Rift is a holo illustration_rare card that currently sells for about $8.97 ungraded, with graded copies ranging from $16.80 at grade 9 to $80.00 at grade 10. A grade 10 copy sells for around $80.00, about 8.9× the $8.97 raw price, so high-grade copies are worth grading.
