3 Ngultrum - Jigme Singye

Bhutan's 1979 coinage program was part of a broader modernization effort under Jigme Singye Wangchuck, who had ascended to the throne in 1972 at age sixteen following his father's sudden death. The 3 Ngultrum denomination is an unusual choice — threefold units rarely appear in decimal systems — reflecting Bhutan's hybrid monetary conventions of that transitional decade, when the country was simultaneously maintaining traditional denominations and adapting to international currency norms.

KM#50 was struck in limited quantities and saw little meaningful circulation in a country where barter remained prevalent in rural areas well into the 1980s.
