The 2004 SP Authentic Mike Piazza #81 is a Baseball card released in 2004. Ungraded copies carry a market value of about $5.92.
An ungraded copy is worth around $5.92, a PSA 9 around $3.25, a PSA 10 (Gem Mint) around $16.99 and a pristine BGS 10 around $22.00. The gem-mint premium is modest (about 2.9× raw), so condition matters here but doesn't completely define the price.
Is it worth grading?
The spread between raw ($5.92) and top-graded ($16.99) 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.
