The 1987 Topps Woolworth Highlights Keith Hernandez #31 is a Baseball card released in 1987. Ungraded copies carry a market value of about $0.53.
An ungraded copy is worth around $0.53, a PSA 9 around $14.62, a PSA 10 (Gem Mint) around $59.15 and a pristine BGS 10 around $77.00. That's roughly a 112× 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 $0.53 and top grades reaching $59.15, 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.
