Methodology

What the signals mean.

A plain-language guide to how Kopa captures collection data, where estimates stop, and which sources support the public World Cup pages.

01
Capture

The collector starts the record

A camera image begins the workflow. The collector reviews the result before deciding what belongs in an album.

02
Interpret

AI-assisted details add context

Kopa can help identify an item and organize descriptive details. AI output should be reviewed, especially when images are unclear or sets contain similar designs.

03
Estimate

Market signals form a range

Estimated values may include ranges, averages, medians, and confidence indicators. They are informational signals—not appraisals or guaranteed sale prices.

04
Organize

The collection remains the source of truth

Owned, missing, duplicate, and wanted states help collectors manage progress. Users can update those states as the physical collection changes.

Limits

Use estimates as context.

Actual collectible prices depend on authenticity, edition, print variation, condition, geography, fees, timing, buyer demand, and the quality of comparable listings.

Condition notes are AI-assisted observations from an image, not professional grading. A photograph may hide surface defects, alterations, or authenticity issues.
