# Figure collection and duplicate tracker — CollectorLedger

Canonical: https://thedollscout.com/workbench/collectorledger
Language: en
Method version: 2026-09-19.2

Count owned figures and duplicates while preserving recorded purchase costs.

## How this tool works

Group by series + figure + variant. Duplicates = max(quantity − 1, 0). Recorded cost = sum(quantity × paid_each), kept separate by currency.

## Input format

- Collection records: `series,figure,variant,quantity,paid_each,currency`
