The 2021 Bowman University Spencer Rattler #28 is a Football card released in 2021. Ungraded copies carry a market value of about $1.04.
An ungraded copy is worth around $1.04, a PSA 9 around $5.00, a PSA 10 (Gem Mint) around $12.64 and a pristine BGS 10 around $16.00. That's roughly a 12× 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 ($1.04) and top-graded ($12.64) 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.
