Team Rocket's Petrel #226 from Destined Rivals is a holo ultra_rare card that currently sells for about $8.99 ungraded, with graded copies ranging from $5.50 at grade 7 to $40.00 at grade 10. A grade 10 copy sells for around $40.00, about 4.4× the $8.99 raw price, so high-grade copies are worth grading.
