The 2025 Topps NBA Hoops 1989 Signature Kenyon Martin Sr. Green Hoops #89S-KM is a Basketball card (Green Hoops parallel) released in 2026. Ungraded copies carry a market value of about $6.77.
An ungraded copy is worth around $6.77, a PSA 9 around $21.02, a PSA 10 (Gem Mint) around $61.62 and a pristine BGS 10 around $80.00. That's roughly a 9.1× 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 $6.77 and top grades reaching $61.62, 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.
