The 2018 Topps Chrome Base Set Buster Posey Sepia Refractor #29 is a Baseball card (Sepia Refractor parallel) released in 2018. Ungraded copies carry a market value of about $2.39.
An ungraded copy is worth around $2.39, a PSA 9 around $6.38, a PSA 10 (Gem Mint) around $29.99 and a pristine BGS 10 around $39.00. That's roughly a 13× 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 ($2.39) and top-graded ($29.99) 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.
