The 1991 Upper Deck Isiah Thomas #451 is a Basketball card released in 1991. Ungraded copies carry a market value of about $1.38.
An ungraded copy is worth around $1.38, a PSA 9 around $11.95, a PSA 10 (Gem Mint) around $26.19 and a pristine BGS 10 around $34.00. 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 ($1.38) and top-graded ($26.19) 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.
