The 1999 Upper Deck PowerDeck Ken Griffey Jr. Auxiliary Power Gold #AUX-1 is a Baseball card (Auxiliary Power Gold parallel) released in 1999. Ungraded copies carry a market value of about $3.73.
An ungraded copy is worth around $3.73, a PSA 9 around $24.39, a PSA 10 (Gem Mint) around $110.33 and a pristine BGS 10 around $143.00. That's roughly a 30× 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 $3.73 and top grades reaching $110.33, 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.
