The europa was a token coinage created in 1928 by, a politician and industrialist from the Nièvre region in France. The currency was promoted by, the elected deputy for the Haute-Loire who, along with Archer, was an influential figure in the European federalist movement. The coins were minted in the name of a hypothetical "Federated States of Europe" (États fédérés d'Europe). Unlike contemporary currencies based on the gold standard, the europa was intended to derive its notional value from its value in labour.
The currency never circulated except unofficially between federalists of the Nièvre region. Two denominations were produced, both depicting Louis Pasteur and a map of Europe on the obverse and reverse respectively: one valued at 1 europa and another at 1/10 of a europa.
