The 2020 Panini Diamond Kings Base Set Bryce Harper Artist Proof Blue #66 is a Baseball card (Artist Proof Blue parallel) released in 2020. Ungraded copies carry a market value of about $1.94.
An ungraded copy is worth around $1.94, a PSA 10 (Gem Mint) around $18.00 and a pristine BGS 10 around $23.00. That's roughly a 9.3× 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 ($1.94) and top-graded ($18.00) 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.
