The 2020-21 Panini Prizm Rookie Penmanship Caleb Martin Silver Prizm #RP-CMT is a Basketball card (Silver Prizm parallel) released in 2021. Ungraded copies carry a market value of about $1.42.
An ungraded copy is worth around $1.42, a PSA 9 around $11.51, a PSA 10 (Gem Mint) around $21.99 and a pristine BGS 10 around $29.00. That's roughly a 15× 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 ($1.42) and top-graded ($21.99) 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.
