The 1970 Bhutanese gold sertum was part of a broader commemorative program issued under Jigme Dorji Wangchuck, the fourth Druk Gyalpo, who had been systematically opening Bhutan to the outside world after decades of near-total isolation. The coins were produced at the Royal Mint in London — Bhutan had no domestic minting capacity at the time — and were intended partly for international collectors rather than domestic circulation.
Jigme Dorji Wangchuck died in July 1972, two years after this issue, making these coins among the last gold pieces authorized under his reign.
