Investment Score
Underground Expedition scores 31/100. 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 10% below our fair value. It sits mid-pack in Celestial Storm by price. 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.
Supply shows both venues — eBay active listings + TCGplayer sellers (distinct units, not summed); the supply-trend gauge is eBay-driven for now, with the TCGplayer trend surfacing once its history is reliable, then blending. Sold/wk is TCGplayer; demand pressure = weekly TCGplayer sales ÷ eBay active listings (soft → hot) — a relative read, not a literal sell-through. Descriptive market context, not a forecast.
