The 2010 Topps Update Shelley Duncan All-Black #US-242 is a Baseball card (All-Black parallel) released in 2010. Ungraded copies carry a market value of about $1.83.

An ungraded copy is worth around $1.83, a PSA 9 around $12.62, a PSA 10 (Gem Mint) around $38.27 and a pristine BGS 10 around $50.00. That's roughly a 21× 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 ($1.83) and top-graded ($38.27) 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.
