The 2017-18 Donruss Optic Base Set Klay Thompson Press Proof Purple #49 is a Basketball card (Press Proof Purple parallel) released in 2017. Ungraded copies carry a market value of about $5.99.
An ungraded copy is worth around $5.99, a PSA 10 (Gem Mint) around $40.00 and a pristine BGS 10 around $52.00. That's roughly a 6.7× 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 ($5.99) and top-graded ($40.00) 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.
