The 2010 Bowman Sterling Buster Posey #23 is a Baseball card released in 2010. Ungraded copies carry a market value of about $31.50.
An ungraded copy is worth around $31.50, a PSA 9 around $51.00, a PSA 10 (Gem Mint) around $271.25 and a pristine BGS 10 around $353.00. That's roughly a 8.6× 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 $31.50 and top grades reaching $271.25, 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.
