Sabrina's Slowbro #60 from Gym Heroes is a 1st edition uncommon card that currently sells for about $10.86 ungraded, with graded copies ranging from $20.56 at grade 7 to $100 at grade 10. A grade 10 copy sells for around $100, about 9.2× the $10.86 raw price, so high-grade copies are worth grading.
