100 Dollars - Hassanal Bolkiah ASEAN 2013 Presidency

Brunei assumed the ASEAN chairmanship in 2013, the first time the sultanate had held the rotating presidency since 2000. The theme Brunei adopted — "Our People, Our Future Together" — reflected ongoing negotiations around the ASEAN Economic Community, which was formally established two years later. These gold commemoratives were issued in strictly limited quantities, consistent with Brunei's practice of producing collector coinage almost exclusively for diplomatic gifting and high-end numismatic markets rather than general circulation.
