The 1994 Upper Deck Mike Piazza Electric Diamond #500 is a Baseball card (Electric Diamond parallel) released in 1994. Ungraded copies carry a market value of about $2.12.
An ungraded copy is worth around $2.12, a PSA 9 around $29.49, a PSA 10 (Gem Mint) around $37.00 and a pristine BGS 10 around $48.00. That's roughly a 17× 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?
The spread between raw ($2.12) and top-graded ($37.00) copies is fairly tight, so grading this card only makes financial sense for truly flawless copies — or for collectors who simply prefer slabbed cards for protection and display.
