The 1994 Upper Deck John Valentin Electric Diamond #373 is a Baseball card (Electric Diamond parallel) released in 1994. Ungraded copies carry a market value of about $2.17.

An ungraded copy is worth around $2.17, a PSA 9 around $22.13, a PSA 10 (Gem Mint) around $102.69 and a pristine BGS 10 around $134.00. That's roughly a 47× 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 $2.17 and top grades reaching $102.69, 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.
