Team Rocket's Nidoking ex #233 from Destined Rivals is a reverse holo illustration_rare card that currently sells for about $91.00 ungraded, with graded copies ranging from $80.00 at grade 7 to $255 at grade 10. A grade 10 copy sells for around $255, about 2.8× the $91.00 raw price, so high-grade copies are worth grading.
