200 Dollars - Hassanal Bolkiah Royal Wedding

Issued to mark the 2004 wedding of Crown Prince Al-Muhtadee Billah, Brunei's first and only heir apparent, to Sarah Salleh — a commoner whose selection broke quietly with dynastic convention in a sultanate where royal marriages had historically involved aristocratic or foreign connections. The ceremony was among the most expensive royal weddings recorded in Southeast Asia that decade, befitting a nation whose oil revenues have sustained one of the highest per-capita GDPs in the world under Hassanal Bolkiah's rule since 1967.

Struck in .9999 fine gold at a troy ounce, this is a presentation piece rather than a circulation issue — Brunei's circulating coinage has never included gold denominations.
