Euro and legacy currencies

The euro was formally introduced on 1 January 1999, in accordance with Article 109 L(4) of the Treaty establishing the European Community.  Initially the euro replaced nine national European currencies, but has subsequently expanded to incorporate further EU member state currencies.  Dates of adoption of the euro in EU member states can be found on the European Central Bank website.

Spot rates for individual legacy currencies are published until the date of their replacement by the euro.
