The 1994 Upper Deck Greg Maddux Electric Diamond #320 is a Baseball card (Electric Diamond parallel) released in 1994. Ungraded copies carry a market value of about $1.79.
An ungraded copy is worth around $1.79, a PSA 9 around $20.62, a PSA 10 (Gem Mint) around $93.65 and a pristine BGS 10 around $122.00. That's roughly a 52× 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 $1.79 and top grades reaching $93.65, 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.
