The 2023 Topps Base Set Pete Alonso Golden Mirror SSP Variation #20 is a Baseball card (Golden Mirror SSP Variation parallel) released in 2023. Ungraded copies carry a market value of about $69.70.
An ungraded copy is worth around $69.70, a PSA 9 around $67.00, a PSA 10 (Gem Mint) around $255.00 and a pristine BGS 10 around $332.00. That's roughly a 3.7× 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 $69.70 and top grades reaching $255.00, 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.
