Professor Turo's Scenario #121 from Prismatic Evolutions is a reverse holo uncommon card that currently sells for about $0.50 ungraded, with graded copies ranging from $10.50 at grade 9 to $40.00 at grade 10. A grade 10 copy sells for around $40.00, about 80× the $0.50 raw price, so high-grade copies are worth grading.
