The 1988 Topps Base Set Keith Comstock Blue #778 is a Baseball card (Blue parallel) released in 1988. Ungraded copies carry a market value of about $1.09.
An ungraded copy is worth around $1.09, a PSA 9 around $5.50, a PSA 10 (Gem Mint) around $129.45 and a pristine BGS 10 around $168.00. That's roughly a 119× 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 $1.09 and top grades reaching $129.45, 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.
