The 2004 Upper Deck Diamond Collection All Star Lineup Frank Thomas #21 is a Baseball card released in 2004. Ungraded copies carry a market value of about $1.30.
An ungraded copy is worth around $1.30, a PSA 10 (Gem Mint) around $39.99 and a pristine BGS 10 around $52.00. That's roughly a 31× 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 ($1.30) and top-graded ($39.99) 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.
