## What it shows

- **507**: territory-currency periods in source
- **41**: EUR tender periods with start dates
- **308**: distinct currency codes in history

A country-to-currency mapping needs a date and a tender flag. A single current currency column loses historical and overlapping use.

## Method

Exact selection: currency EUR, tender true, start date present. Printed dates are source currency-use dates, not necessarily cash-introduction dates or legal accession dates. Territorial overlap is retained.
