The 2021 Bowman University Spencer Rattler Shimmer #28 is a Football card (Shimmer parallel) released in 2021. Ungraded copies carry a market value of about $3.42.
An ungraded copy is worth around $3.42, a PSA 9 around $3.25, a PSA 10 (Gem Mint) around $11.50 and a pristine BGS 10 around $15.00. That's roughly a 3.4× 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 ($3.42) and top-graded ($11.50) 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.
