The 2026 Topps Series 2 1991 All-Stars Buster Posey Green All Star Game #91AS-18 is a Baseball card (Green All Star Game parallel) released in 2026. Ungraded copies carry a market value of about $6.11.
An ungraded copy is worth around $6.11, a PSA 9 around $19.74, a PSA 10 (Gem Mint) around $58.07 and a pristine BGS 10 around $75.00. That's roughly a 9.5× 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 $6.11 and top grades reaching $58.07, 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.
