Duraludon VMAX #TG21 from Silver Tempest Trainer Gallery is a reverse holo holo_rare card that currently sells for about $9.67 ungraded, with graded copies ranging from $7.51 at grade 7 to $65.00 at grade 10. A grade 10 copy sells for around $65.00, about 6.7× the $9.67 raw price, so high-grade copies are worth grading.
