The 2018 Lost Thunder Sigilyph-GX #98 is a Pokémon card released in 2018. Ungraded copies carry a market value of about $3.16.
An ungraded copy is worth around $3.16, a PSA 9 around $33.23 and a PSA 10 (Gem Mint) around $162.50. That's roughly a 51× 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 $3.16 and top grades reaching $162.50, 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.
