Stronger supporting evidence
106 recordsMore consistent, more usable evidence with fewer major limitations. It remains an estimate, never a guaranteed trade price.
Confidence guide
An estimate is only as strong as its evidence.
Data confidence describes the evidence behind an estimate. It is separate from price stability, rarity, or whether the price will rise.
Useful direction, meaningful limits
150 recordsThe evidence supports a practical range, but the sample, consistency, recency, or exact comparability leaves room for caution.
A starting point, not a verdict
398 recordsLimited or weaker evidence. Check current listings and negotiate carefully before relying on the displayed range.
Confidence is not stability
A well-observed item can still trade across a wide band. High data confidence means the ledger has stronger evidence; it does not mean every trader agrees on one exact price. Stability is shown separately as Stable, Variable, or Volatile.
What affects confidence
Signal strength
A clear supported trade carries more weight than an unsupported asking price.
Consistency
Evidence that clusters around a similar range is easier to use than widely conflicting observations.
Comparability
The exact item, roll, variant, currency, platform, and market conditions need to be genuinely comparable.
