The 1994 Upper Deck Mike Piazza Electric Diamond #33 is a Baseball card (Electric Diamond parallel) released in 1994. Ungraded copies carry a market value of about $0.99.
An ungraded copy is worth around $0.99, a PSA 10 (Gem Mint) around $75.00 and a pristine BGS 10 around $98.00. That's roughly a 76× 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 $0.99 and top grades reaching $75.00, 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.
