"The Sultan of Brunei is the head of state and absolute monarch of Brunei. He is also head of government in his capacity as Prime Minister. Since independence from the British in 1984, only one Sultan has reigned, though the royal institution dates back to the 14th century."
"This rare vintage set has been one of very earliest issued by the Royal Mint (UK) before the sultanate's independence in 1984. Very limited quantities of such sets has been released out into public collections. The coins are still in original plush box, and individually sealed (see pictures). Totally new and completely untouched aged approx. > 45+ years old, this is a definite rarity."
