The 1997 Topps Season's Best Mark McGwire #SB6 is a Baseball card released in 1997. Ungraded copies carry a market value of about $2.20.
An ungraded copy is worth around $2.20, a PSA 9 around $22.50, a PSA 10 (Gem Mint) around $118.70 and a pristine BGS 10 around $154.00. That's roughly a 54× 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 $2.20 and top grades reaching $118.70, 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.
