The 2004 Leaf Cornerstones Tom Glavine / Mike Piazza Materials #CS-6 is a Baseball card (Materials parallel) released in 2004. Ungraded copies carry a market value of about $3.26.

An ungraded copy is worth around $3.26, a PSA 9 around $18.25, a PSA 10 (Gem Mint) around $70.10 and a pristine BGS 10 around $91.00. That's roughly a 22× premium for a gem-mint copy over raw — one of the clearest signals that condition-sensitive buyers dominate this card's market.

Is it worth grading?

With raw copies near $3.26 and top grades reaching $70.10, grading a sharp copy of this card can clearly pay for itself — the spread comfortably covers a typical ~$25.00 grading fee. The catch: only submit copies with strong centering, clean corners, and unmarked surfaces, because anything below a 9 usually erases the math.
