The 2018 Forbidden Light Dialga-GX #138 is a Pokémon card released in 2018. Ungraded copies carry a market value of about $162.00.
An ungraded copy is worth around $162.00, a PSA 9 around $160.00 and a PSA 10 (Gem Mint) around $809.37. That's roughly a 5.0× 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 $162.00 and top grades reaching $809.37, 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.
