The 2024 Topps Cosmic Chrome Galactic Greatness Buster Posey #GG-18 is a Baseball card released in 2024. Ungraded copies carry a market value of about $1.95.
An ungraded copy is worth around $1.95, a PSA 9 around $12.66, a PSA 10 (Gem Mint) around $36.29 and a pristine BGS 10 around $47.00. That's roughly a 19× 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 ($1.95) and top-graded ($36.29) 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.
