100 Euro

The 1997 date places this as a specimen or trial note from the preparatory phase before euro banknotes entered circulation in January 2002 — the European Monetary Institute was dissolved and replaced by the ECB in June 1998, well before any public issuance. Notes bearing EMI attribution were never released to the public; they were produced strictly for testing printing standards, security feature evaluation, and central bank familiarization programs across the twelve adopting states.

The single listed security feature — watermark only — almost certainly reflects incomplete cataloging rather than the actual specification, as even early test printings incorporated multiple features under evaluation.
