The 1990 Topps Bo Knows Yardage Disclaimer Back #522 is a Football card (Disclaimer Back parallel) released in 1990. Ungraded copies carry a market value of about $5.41.
An ungraded copy is worth around $5.41, a PSA 9 around $44.00, a PSA 10 (Gem Mint) around $73.57 and a pristine BGS 10 around $96.00. That's roughly a 14× 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 $5.41 and top grades reaching $73.57, 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.
