Professor Burnet #TG26 from Silver Tempest Trainer Gallery is a holo rare card that currently sells for about $4.94 ungraded, with graded copies ranging from $9.38 at grade 7 to $38.00 at grade 10. A grade 10 copy sells for around $38.00, about 7.7× the $4.94 raw price, so high-grade copies are worth grading.
