The 2005 Donruss Diamond Kings Don Mattingly #294 is a Baseball card released in 2005. Ungraded copies carry a market value of about $2.05.
An ungraded copy is worth around $2.05, a PSA 9 around $14.65, a PSA 10 (Gem Mint) around $51.64 and a pristine BGS 10 around $67.00. That's roughly a 25× 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 ($2.05) and top-graded ($51.64) 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.
