The 2003 SP Authentic Tim Duncan #77 is a Basketball card released in 2003. Ungraded copies carry a market value of about $1.40.
An ungraded copy is worth around $1.40, a PSA 9 around $8.00, a PSA 10 (Gem Mint) around $26.60 and a pristine BGS 10 around $35.00. That's roughly a 19× 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 ($1.40) and top-graded ($26.60) 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.
