The 1997 Flair Showcase Diamond Cuts Mark McGwire #11 is a Baseball card released in 1997. Ungraded copies carry a market value of about $39.14.
An ungraded copy is worth around $39.14, a PSA 9 around $42.50, a PSA 10 (Gem Mint) around $140.00 and a pristine BGS 10 around $182.00. That's roughly a 3.6× 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 $39.14 and top grades reaching $140.00, 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.
