Xerneas-EX #97 from Celebrations: Classic Collection is a reverse holo common card that currently sells for about $4.00 ungraded, with graded copies ranging from $4.99 at grade 7 to $6.50 at grade 10. A grade 10 copy sells for around $6.50 vs $4.00 raw. That's a modest premium, so grading only pays off for near-perfect copies.
