The 1998 SP Authentic Tim Duncan #75 is a Basketball card released in 1998. Ungraded copies carry a market value of about $1.26.
An ungraded copy is worth around $1.26, a PSA 9 around $16.51, a PSA 10 (Gem Mint) around $33.00 and a pristine BGS 10 around $43.00. That's roughly a 26× 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 ($1.26) and top-graded ($33.00) 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.
