The 2021 Bowman University Blake Corum Shimmer #54 is a Football card (Shimmer parallel) released in 2021. Ungraded copies carry a market value of about $4.06.
An ungraded copy is worth around $4.06, a PSA 10 (Gem Mint) around $42.54 and a pristine BGS 10 around $55.00. That's roughly a 10× 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 ($4.06) and top-graded ($42.54) 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.
