The 2023 Topps Museum Collection Base Set Mike Piazza #21 is a Baseball card released in 2023. Ungraded copies carry a market value of about $1.99.
An ungraded copy is worth around $1.99, a PSA 9 around $12.45, a PSA 10 (Gem Mint) around $34.81 and a pristine BGS 10 around $45.00. 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 ($1.99) and top-graded ($34.81) 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.
