The 2008 Finest Ken Griffey Jr. Blue Refractor #18 is a Baseball card (Blue Refractor parallel) released in 2008. Ungraded copies carry a market value of about $55.00.
An ungraded copy is worth around $55.00, a PSA 10 (Gem Mint) around $340.00 and a pristine BGS 10 around $442.00. That's roughly a 6.2× 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 $55.00 and top grades reaching $340.00, 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.
