Investment Score
Dialga GX scores 46/100. We're withholding a letter grade because it has no PSA-10 graded price yet, so the score leans on demand signals. It's trading 63% above our fair value. That puts it among the most valuable cards in Forbidden Light. It trades thinly.

This is a snapshot of demand fundamentals, not a forecast and not financial advice. "Gaining steam" just shows that the price has moved recently, not that it'll keep moving. The score measures durability, not how a card behaves in a crash. And keep an eye out for reprints, which can crash a chase card fast no matter how high the grade. Scores compare cards within the modern era (Mega Evolution, Scarlet & Violet, Sword & Shield) — not against vintage.

Market
Supply & Demand
Supply is the TCGplayer listing count; demand pressure = weekly TCGplayer sales ÷ listings (soft → hot), a single-venue sell-through read. The supply-trend gauge reads eBay where we have it, with the TCGplayer listings trend surfacing as its history matures. Descriptive market context, not a forecast.
