The 2018 Panini Obsidian Klay Thompson Purple #66 is a Basketball card (Purple parallel) released in 2018. Ungraded copies carry a market value of about $6.56.
An ungraded copy is worth around $6.56, a PSA 9 around $13.01, a PSA 10 (Gem Mint) around $189.95 and a pristine BGS 10 around $247.00. That's roughly a 29× 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 $6.56 and top grades reaching $189.95, 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.
