1998 Topps Frank Thomas Diamondbacks Inaugural #20 value & prices

The 1998 Topps Frank Thomas Diamondbacks Inaugural #20 is a Baseball card (Diamondbacks Inaugural parallel) released in 1998. Ungraded copies carry a market value of about $4.31.

An ungraded copy is worth around $4.31, a PSA 10 (Gem Mint) around $80.00 and a pristine BGS 10 around $104.00. That's roughly a 19× 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 $4.31 and top grades reaching $80.00, 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.
