The 2025 Donruss Diamond Kings Theo Gillen #9 is a Baseball card released in 2025. Ungraded copies carry a market value of about $8.44.
An ungraded copy is worth around $8.44, a PSA 9 around $22.47, a PSA 10 (Gem Mint) around $62.99 and a pristine BGS 10 around $82.00. That's roughly a 7.5× 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 $8.44 and top grades reaching $62.99, 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.
