The 1986 Fleer Baseball's Best Don Mattingly #21 is a Baseball card released in 1986. Ungraded copies carry a market value of about $1.43.
An ungraded copy is worth around $1.43, a PSA 9 around $18.28, a PSA 10 (Gem Mint) around $64.50 and a pristine BGS 10 around $84.00. That's roughly a 45× 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 $1.43 and top grades reaching $64.50, 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.
