The 2005 Finest Carlos Guillen Black Refractor #31 is a Baseball card (Black Refractor parallel) released in 2005. Ungraded copies carry a market value of about $0.84.
An ungraded copy is worth around $0.84, a PSA 10 (Gem Mint) around $49.99 and a pristine BGS 10 around $65.00. That's roughly a 60× 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 ($0.84) 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.
