Duraludon VMAX #TG30 from Silver Tempest Trainer Gallery is a rare card that currently sells for about $3.37 ungraded, with graded copies ranging from $6.25 at grade 7 to $37.77 at grade 10. A grade 10 copy sells for around $37.77, about 11× the $3.37 raw price, so high-grade copies are worth grading.
