The 1991-92 Upper Deck Base Set Isiah Thomas #91 is a Sports card. Ungraded copies carry a market value of about $1.49.
An ungraded copy is worth around $1.49, a PSA 9 around $19.00 and a PSA 10 (Gem Mint) around $150.00. That's roughly a 101× 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 $1.49 and top grades reaching $150.00, 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.
