The 2021 Topps Chrome Base Set Buster Posey Magenta Speckle Refractor #29 is a Baseball card (Magenta Speckle Refractor parallel) released in 2021. Ungraded copies carry a market value of about $4.11.
An ungraded copy is worth around $4.11, a PSA 10 (Gem Mint) around $49.99 and a pristine BGS 10 around $65.00. That's roughly a 12× 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 ($4.11) and top-graded ($49.99) 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.
