The 2018 Ultra Prism Dialga-GX #100 is a Pokémon card released in 2018. Ungraded copies carry a market value of about $12.50.
An ungraded copy is worth around $12.50, a PSA 9 around $89.75 and a PSA 10 (Gem Mint) around $500.00. That's roughly a 40× 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 $12.50 and top grades reaching $500.00, 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.
