Giovanni's Machoke #42 from Gym Challenge is a 1st edition uncommon card that currently sells for about $6.90 ungraded, with graded copies ranging from $3.25 at grade 7 to $99.99 at grade 10. A grade 10 copy sells for around $99.99, about 15× the $6.90 raw price, so high-grade copies are worth grading.
