The 1989 Pro Set Brian Bosworth Error #391 is a Football card (Error parallel) released in 1989. Ungraded copies carry a market value of about $2.49.
An ungraded copy is worth around $2.49, a PSA 9 around $36.10, a PSA 10 (Gem Mint) around $36.27 and a pristine BGS 10 around $47.00. That's roughly a 15× 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 ($2.49) and top-graded ($36.27) 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.
