ECU Narwhal

Germany never adopted the ECU as legal tender — it remained a unit of account used in European exchange rate mechanisms, not a circulating currency. A handful of European nations issued ECU-denominated collector pieces in the 1990s as the continent moved toward monetary union, and Germany participated with several such issues. The "Narwhal" designation here almost certainly refers to a medallic or collector series rather than any official Bundesbank emission, and copper-nickel at this diameter places it firmly outside standard German coinage specifications of the period.
