The 1989 Upper Deck Base Set Frank Viola Twins Checklist #691 is a Baseball card (Twins Checklist parallel) released in 1989. Ungraded copies carry a market value of about $1.55.
An ungraded copy is worth around $1.55, a PSA 9 around $18.00, a PSA 10 (Gem Mint) around $104.33 and a pristine BGS 10 around $136.00. That's roughly a 67× 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 $1.55 and top grades reaching $104.33, 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.
