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.$1,424.93

Grading

Buy raw, grade with PSA, sell as a slab. The upside if it grades PSA 10, after fee and turnaround.
Best case — the return if this card grades PSA 10, net of the $80.00 fee and a ~8-week turnaround haircut. PSA 10s happen about 36% of the time (the gem rate above); on a miss you roughly recover the raw cost.

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 trend · coming soon — banking PSA-10 population data.
Demand is PSA-10 sales (eBay sold); supply is the PSA-10 population, so demand pressure here is turnover — % of the population sold per week. A supply trend follows as we bank PSA-10 population history. Descriptive, not a forecast.
