The 1969 Topps Jerry Koosman #434 is a Baseball card released in 1969. Ungraded copies carry a market value of about $2.81.
An ungraded copy is worth around $2.81, a PSA 9 around $256.78, a PSA 10 (Gem Mint) around $417.53 and a pristine BGS 10 around $543.00. That's roughly a 149× 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 $2.81 and top grades reaching $417.53, 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.
