The 2008 Spx Ken Griffey Jr. American Hero Ken Griffey Jr. #KG39 is a Baseball card released in 2008. Ungraded copies carry a market value of about $8.00.
An ungraded copy is worth around $8.00, a PSA 9 around $24.12, a PSA 10 (Gem Mint) around $85.31 and a pristine BGS 10 around $111.00. That's roughly a 11× 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 $8.00 and top grades reaching $85.31, 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.
