The 1986 Topps Jerry Koosman #505 is a Baseball card released in 1986. Ungraded copies carry a market value of about $1.17.
An ungraded copy is worth around $1.17, a PSA 9 around $17.80, a PSA 10 (Gem Mint) around $100.34 and a pristine BGS 10 around $130.00. That's roughly a 86× 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 $1.17 and top grades reaching $100.34, 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.
