The 2019 Panini Prizm Rookie Signatures Grant Williams Blue Shimmer #GWL is a Basketball card (Blue Shimmer parallel) released in 2019. Ungraded copies carry a market value of about $6.63.
An ungraded copy is worth around $6.63, a PSA 10 (Gem Mint) around $105.00 and a pristine BGS 10 around $137.00. That's roughly a 16× 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 $6.63 and top grades reaching $105.00, 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.
