Editorial Policy & Corrections
Kopa publishes collector references to make sticker data easier to understand. This policy explains which evidence we prefer, where interpretation begins and how corrections are reviewed.
Reviewed 2026-07-13
4 principlesverified collection data
Facts and estimates stay separate
Checklist facts are sourced. Values, condition notes and scarcity interpretations are qualified and never presented as guarantees.
Dates remain visible
Time-sensitive reference pages carry a review date, and material updates refresh the public record.
Corrections are welcome
Collectors can report an issue with a URL, market, printed evidence and a description of the proposed correction.
Evidence hierarchy
Official collection guides, printed checklists and product pages are preferred. Reputable reporting can support launch context. Community posts help identify questions, but material claims require corroboration.
Review and change control
References record the source and review date. When a count, code, product relationship or market detail changes, the affected page should be updated and the change recorded.
AI-assisted information
AI-assisted identification, condition notes and values are reviewed as suggestions. They are not authentication, professional grading, appraisals or guaranteed sale prices.
Submit a correction
Include the affected URL, exact statement, market or edition, and a photograph or primary-source link when available. Kopa reviews the evidence before changing a public reference.
