The 1989 Topps Mark Kelso #56 is a Football card released in 1989. Ungraded copies carry a market value of about $1.69.

An ungraded copy is worth around $1.69, a PSA 9 around $23.07, a PSA 10 (Gem Mint) around $111.53 and a pristine BGS 10 around $145.00. That's roughly a 66× 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 $1.69 and top grades reaching $111.53, 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.
