Report An Error
Send the page URL, card name, exact printing, collector number, finish, condition, source marketplace, observed value, and what appears wrong.
A data refresh is not always an editorial correction. If a marketplace updates normally, the page may change without a correction note.
Review Process
Material corrections should preserve the historical record instead of hiding failed, cooled, or invalidated signals.
If a trend outcome changes because later evidence contradicts the original signal, the outcome should remain visible as cooled, invalidated, unresolved, or insufficient data.
