Druddigon #TG09 from Silver Tempest Trainer Gallery is a reverse holo holo_rare card that currently sells for about $2.99 ungraded, with graded copies ranging from $8.00 at grade 7 to $75.00 at grade 10. A grade 10 copy sells for around $75.00, about 25× the $2.99 raw price, so high-grade copies are worth grading.
