Marshadow & Machamp-GX #221 from Unbroken Bonds is a reverse holo rare card that currently sells for about $40.00 ungraded, with graded copies ranging from $32.00 at grade 7 to $250 at grade 10. A grade 10 copy sells for around $250, about 6.3× the $40.00 raw price, so high-grade copies are worth grading.
