Dark Dragonair #31 from Team Rocket Returns is a reverse holo uncommon card that currently sells for about $5.40 ungraded, with graded copies ranging from $14.00 at grade 7 to $84.99 at grade 10. A grade 10 copy sells for around $84.99, about 16× the $5.40 raw price, so high-grade copies are worth grading.
