Heal Energy #8 from POP Series 4 is a uncommon card that currently sells for about $7.92 ungraded, with graded copies ranging from $12.68 at grade 9 to $14.00 at grade 9.5. A grade 9.5 copy sells for around $14.00 vs $7.92 raw. That's a modest premium, so grading only pays off for near-perfect copies.
