Professor Turo's Scenario #257 from Paradox Rift is a illustration_rare card that currently sells for about $6.24 ungraded, with graded copies ranging from $13.00 at grade 9 to $35.00 at grade 10. A grade 10 copy sells for around $35.00, about 5.6× the $6.24 raw price, so high-grade copies are worth grading.
