Giovanni's Persian #8 from Gym Challenge is a 1st edition holo holo_rare card that currently sells for about $99.37 ungraded, with graded copies ranging from $92.00 at grade 7 to $4,000 at grade 10. A grade 10 copy sells for around $4,000, about 40× the $99.37 raw price, so high-grade copies are worth grading.
