The 1991 Upper Deck Denny's Grand Slam Cal Ripken Jr. #20 is a Baseball card released in 1991. Ungraded copies carry a market value of about $1.52.
An ungraded copy is worth around $1.52, a PSA 9 around $23.46, a PSA 10 (Gem Mint) around $112.80 and a pristine BGS 10 around $147.00. That's roughly a 74× 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 $1.52 and top grades reaching $112.80, 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.
