PSA 10 slab?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 30–60 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 “vs Fair Value” figures measure against different benchmarks, so they can point different directions without disagreeing. Raw is judged against the graded market — undervalued means the raw card is cheap relative to its PSA 10. Slab is judged against fundamentals — overvalued means the PSA 10 itself looks rich versus print scarcity, grading rates, and demand. Both can be true at once. 483 PSA 10 pop · 37% gem

Active listings + the supply-trend gauge are eBay; sold/wk is TCGplayer. Demand pressure = weekly TCGplayer sales ÷ eBay active listings (soft → hot) — a relative read, not a literal sell-through, since the two venues differ (but track closely). Descriptive market context, not a forecast.
