50 Pence - Elizabeth II European Union, Silver Proof

This piece was struck to mark the United Kingdom's presidency of the European Union Council, which Britain held in the first half of 1998 — the same six-month window in which eleven other member states locked exchange rates in preparation for euro adoption on 1 January 1999. Britain, of course, was not among them. The proof issue in silver thus occupies a quietly awkward historical position: a commemorative struck by a country that had negotiated its opt-out from the very monetary union it was presiding over.

The extended date range reflects restrikes for collector sets rather than a continuous mintage.
