1988 Topps Brian Brennan #91 value & prices

The 1988 Topps Brian Brennan #91 is a Football card released in 1988. Ungraded copies carry a market value of about $1.70.

An ungraded copy is worth around $1.70, a PSA 9 around $13.20, a PSA 10 (Gem Mint) around $52.07 and a pristine BGS 10 around $68.00. That's roughly a 31× 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 $1.70 and top grades reaching $52.07, 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.
