Darkness Energy #111 from Black & White is a reverse holo common card that currently sells for about $1.81 ungraded, with graded copies ranging from $8.50 at grade 9 to $9.00 at grade 9.5. A grade 9.5 copy sells for around $9.00, about 5× the $1.81 raw price, so high-grade copies are worth grading.
