Fierce Guardianship #489 from Commander Masters is a etched foil rare card that currently sells for about $101 ungraded, with graded copies ranging from $75.00 at grade 9 to $83.00 at grade 9.5. A grade 9.5 copy sells for around $83.00 vs $101 raw. That's a modest premium, so grading only pays off for near-perfect copies.
