The 2018 Topps Legends in the Making Buster Posey Blue #BP is a Baseball card (Blue parallel) released in 2018. Ungraded copies carry a market value of about $1.59.
An ungraded copy is worth around $1.59, a PSA 10 (Gem Mint) around $39.99 and a pristine BGS 10 around $52.00. That's roughly a 25× 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 ($1.59) and top-graded ($39.99) 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.
