Team Rocket's Crobat ex #217 from Destined Rivals is a ultra_rare card that currently sells for about $3.99 ungraded, with graded copies ranging from $21.00 at grade 9 to $42.99 at grade 10. A grade 10 copy sells for around $42.99, about 11× the $3.99 raw price, so high-grade copies are worth grading.
