The 2025 Topps Cosmic Chrome Extraterrestrial Talent Coby Mayo #ET-27 is a Baseball card released in 2025. Ungraded copies carry a market value of about $1.87.
An ungraded copy is worth around $1.87, a PSA 9 around $7.00, a PSA 10 (Gem Mint) around $37.31 and a pristine BGS 10 around $49.00. That's roughly a 20× 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 ($1.87) and top-graded ($37.31) 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.
