Confidence Tiers
HIGH means fresh, aligned source evidence supports the price. MODERATE means the price has useful support but still needs normal version and source checks. LOW means the price is harder to trust because source coverage, agreement, freshness, or mapping is weak.
ILLIQUID means shallow supply makes one listing or one sale too influential. OUTLIER_RISK means a source or price move may be distorted.
What Not To Infer
LOW does not mean the card is bad or cheap. It means the price needs verification before you trust it.
A HIGH confidence price is still not advice. Check the exact version, condition, finish, current listings, fees, and source timestamps before buying or selling.
