The 2018 Topps Chrome Base Set Buster Posey Negative Refractor #29 is a Baseball card (Negative Refractor parallel) released in 2018. Ungraded copies carry a market value of about $5.00.
An ungraded copy is worth around $5.00, a PSA 10 (Gem Mint) around $43.42 and a pristine BGS 10 around $56.00. That's roughly a 8.7× 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 ($5.00) and top-graded ($43.42) 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.
