The 2025-26 O-Pee-Chee Platinum Retro Matthew Knies Rainbow #R-18 is a Hockey card (Rainbow parallel) released in 2026. Ungraded copies carry a market value of about $1.48.
An ungraded copy is worth around $1.48, a PSA 9 around $12.31, a PSA 10 (Gem Mint) around $36.61 and a pristine BGS 10 around $48.00. That's roughly a 25× 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 ($1.48) and top-graded ($36.61) 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.
