250 Ngultrums - Jigme Singye Wonders of the World - Pyramids

Bhutan's Royal Monetary Authority issued a sprawling series of collector coins throughout the 1990s and 2000s targeting the international numismatic market — a reliable revenue stream for small nations with no realistic export economy in precious metals. These "Wonders of the World" pieces were produced almost certainly by a European contract mint and never intended for domestic circulation in a country where the ngultrum's everyday denominations run to single digits.

The Great Pyramid at Giza is the only surviving structure of the original Seven Wonders, a fact established by ancient sources including Antipater of Sidon's second-century BC list.
