The 1998 Bowman's Best Mike Piazza Refractor #21 is a Baseball card (Refractor parallel) released in 1998. Ungraded copies carry a market value of about $24.50.
An ungraded copy is worth around $24.50, a PSA 10 (Gem Mint) around $297.11 and a pristine BGS 10 around $386.00. That's roughly a 12× 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 $24.50 and top grades reaching $297.11, 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.
