PSA 10
How Market is measured The Market value is a robust median of PSA 10 sold prices, a 7-day window when the card sells ≥5/week, widening to 30 to 60 days for thin volume, with an outlier filter. The chart plots the individual sales, so a recent spike can ride above this median. Reading raw vs. slab The two verdicts measure against different benchmarks, so they can point different directions without disagreeing. Raw is judged against the graded market, so a discount means the raw card is cheap relative to its PSA 10. Slab is judged against fundamentals, so a premium means the PSA 10 itself looks rich versus print scarcity, grading rates, and demand. Both can be true at once.$64.99

- Stability3.5
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 & 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.
