The 2018 Topps Chrome Base Set Ryan McMahon Purple Refractor #21 is a Baseball card (Purple Refractor parallel) released in 2018. Ungraded copies carry a market value of about $3.90.
An ungraded copy is worth around $3.90, a PSA 10 (Gem Mint) around $25.00 and a pristine BGS 10 around $33.00. That's roughly a 6.4× 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 ($3.90) and top-graded ($25.00) 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.
