The 2019 Panini Donruss Optic Signature Series Isaiah Roby Purple #IRB is a Basketball card released in 2019. Ungraded copies carry a market value of about $3.56.
An ungraded copy is worth around $3.56, a PSA 10 (Gem Mint) around $20.05 and a pristine BGS 10 around $26.00. That's roughly a 5.6× 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 ($3.56) and top-graded ($20.05) 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.
