The 1999 Sports Illustrated Greats of the Game Autographs Jim Lonborg is a Baseball card released in 1999. Ungraded copies carry a market value of about $6.00.
An ungraded copy is worth around $6.00, a PSA 9 around $33.12, a PSA 10 (Gem Mint) around $159.05 and a pristine BGS 10 around $207.00. That's roughly a 27× 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 $6.00 and top grades reaching $159.05, 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.
