The 1991 Upper Deck Alvin Harper #634 is a Football card released in 1991. Ungraded copies carry a market value of about $1.35.
An ungraded copy is worth around $1.35, a PSA 9 around $16.99, a PSA 10 (Gem Mint) around $30.49 and a pristine BGS 10 around $40.00. That's roughly a 23× 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 ($1.35) and top-graded ($30.49) 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.
