Serperior V #TG13 from Silver Tempest Trainer Gallery is a holo holo_rare card that currently sells for about $15.06 ungraded, with graded copies ranging from $10.50 at grade 7 to $65.00 at grade 10. A grade 10 copy sells for around $65.00, about 4.3× the $15.06 raw price, so high-grade copies are worth grading.
