The 2002 Just Prospects Joe Mauer #21 is a Baseball card released in 2002. Ungraded copies carry a market value of about $2.13.
An ungraded copy is worth around $2.13, a PSA 9 around $16.14, a PSA 10 (Gem Mint) around $61.91 and a pristine BGS 10 around $80.00. 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 $2.13 and top grades reaching $61.91, 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.
