Team Rocket's Nidoking ex #216 from Destined Rivals is a holo ultra_rare card that currently sells for about $3.94 ungraded, with graded copies ranging from $16.00 at grade 7 to $72.98 at grade 10. A grade 10 copy sells for around $72.98, about 19× the $3.94 raw price, so high-grade copies are worth grading.
