The 2008 SP Authentic Tim Duncan Gold #21 is a Basketball card (Gold parallel) released in 2008. Ungraded copies carry a market value of about $13.52.
An ungraded copy is worth around $13.52, a PSA 9 around $35.37, a PSA 10 (Gem Mint) around $53.90 and a pristine BGS 10 around $70.00. That's roughly a 4.0× 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 ($13.52) and top-graded ($53.90) 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.
