Team Rocket's Proton #227 from Destined Rivals is a ultra_rare card that currently sells for about $2.97 ungraded, with graded copies ranging from $14.00 at grade 9 to $27.00 at grade 10. A grade 10 copy sells for around $27.00, about 9.1× the $2.97 raw price, so high-grade copies are worth grading.
