The 1998 Topps Mystery Finest Ken Griffey Jr. Borderless #M20 is a Baseball card (Borderless parallel) released in 1998. Ungraded copies carry a market value of about $22.75.
An ungraded copy is worth around $22.75, a PSA 9 around $71.00, a PSA 10 (Gem Mint) around $317.25 and a pristine BGS 10 around $412.00. That's roughly a 14× 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 $22.75 and top grades reaching $317.25, 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.
