The 1989 Pro Set Jerome Brown #312 is a Football card released in 1989. Ungraded copies carry a market value of about $1.09.
An ungraded copy is worth around $1.09, a PSA 9 around $11.82, a PSA 10 (Gem Mint) around $56.99 and a pristine BGS 10 around $74.00. That's roughly a 52× 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?
With raw copies near $1.09 and top grades reaching $56.99, grading a sharp copy of this card can clearly pay for itself — the spread comfortably covers a typical ~$25.00 grading fee. The catch: only submit copies with strong centering, clean corners, and unmarked surfaces, because anything below a 9 usually erases the math.
