The 2018 Topps Chrome Base Set Ryan McMahon Negative Refractor #21 is a Baseball card (Negative Refractor parallel) released in 2018. Ungraded copies carry a market value of about $4.71.
An ungraded copy is worth around $4.71, a PSA 10 (Gem Mint) around $18.94 and a pristine BGS 10 around $25.00. That's roughly a 4.0× 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 ($4.71) and top-graded ($18.94) 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.
