The 2020 Topps Project 2020 Mark McGwire #234 is a Baseball card released in 2020. Ungraded copies carry a market value of about $8.88.
An ungraded copy is worth around $8.88, a PSA 9 around $4.99, a PSA 10 (Gem Mint) around $30.00 and a pristine BGS 10 around $39.00. That's roughly a 3.4× 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 ($8.88) and top-graded ($30.00) 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.
