Team Rocket's Nidoking ex #216 from Destined Rivals is a ultra_rare card that currently sells for about $5.00 ungraded, with graded copies ranging from $20.10 at grade 9 to $52.69 at grade 10. A grade 10 copy sells for around $52.69, about 11× the $5.00 raw price, so high-grade copies are worth grading.
