Mewtwo-EX #54 from Celebrations: Classic Collection is a reverse holo common card that currently sells for about $9.38 ungraded, with graded copies ranging from $11.50 at grade 7 to $75.00 at grade 10. A grade 10 copy sells for around $75.00, about 8× the $9.38 raw price, so high-grade copies are worth grading.
