The 1998 SP Authentic Grant Hill #31 is a Basketball card released in 1998. Ungraded copies carry a market value of about $1.66.
An ungraded copy is worth around $1.66, a PSA 9 around $8.64, a PSA 10 (Gem Mint) around $39.99 and a pristine BGS 10 around $52.00. That's roughly a 24× 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 ($1.66) 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.
