The 2018 Panini Obsidian Klay Thompson #66 is a Basketball card released in 2018. Ungraded copies carry a market value of about $3.25.
An ungraded copy is worth around $3.25, a PSA 10 (Gem Mint) around $10.50 and a pristine BGS 10 around $14.00. That's roughly a 3.2× 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 ($3.25) and top-graded ($10.50) 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.
