The 2020-21 Panini Mosaic Jam Masters LeBron James Reactive Blue #10 is a Basketball card (Reactive Blue parallel) released in 2020. Ungraded copies carry a market value of about $28.75.
An ungraded copy is worth around $28.75, a PSA 9 around $62.50, a PSA 10 (Gem Mint) around $290.00 and a pristine BGS 10 around $377.00. That's roughly a 10× 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 $28.75 and top grades reaching $290.00, 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.
