How it works
A ledger, not a guess.
Values in Kollektra are entered by people and supported by recorded sales. Nothing is estimated for you behind the scenes.
- 01
Catalog the piece
Record the details that matter: name, category, condition, images and notes, in one consistent entry.
- 02
Record valuations over time
Add dated valuations as the market moves. The history stays intact, so you can see how a piece has changed.
- 03
Attach price evidence
Link auction results and eBay sales to a valuation, so every figure has comparable sales behind it.
Supporting evidence
- Auction resultsource + date
- eBay sold listinglink + price
Provenance for prices

A number on its own is an opinion. Kollektra keeps the sales that informed it right beside the valuation, so anyone reviewing the catalog can follow the reasoning.
