50 Dollars - Elizabeth II Villa Tugendhat

Villa Tugendhat in Brno was completed in 1930 by Ludwig Mies van der Rohe, commissioned by Fritz and Grete Tugendhat. The family fled after the Nazi occupation of Czechoslovakia in 1939; the villa subsequently served as a Gestapo headquarters and later as a stable for horses belonging to a Soviet military unit. It was inscribed as a UNESCO World Heritage Site in 2001.

Niue's platinum issues in this architectural series are struck in extremely limited quantities — the island's numismatic program is managed by the New Zealand Post, and platinum releases typically see mintages well under 100 pieces.
