1 Ringgit - Agong XIII Parliament

Malaysia's thirteenth Yang di-Pertuan Agong, Mizan Zainal Abidin, ascended to the five-year rotating kingship in 2006. The position cycles among the hereditary rulers of Malaysia's nine royal states — a constitutional arrangement unique in the world, formalized at independence in 1957. Nordic gold, the copper-aluminum-zinc alloy developed by the Swedish firm Nordic AB in the 1990s, was adopted by Bank Negara partly for its resistance to counterfeiting and its distinctive golden appearance without the cost of actual gold content.

KM#159 replaced the earlier polymer one-ringgit note, which was itself discontinued in 1993 after a relatively short run.
