50 Ngultrums St Paul's Walden Bury

St Paul's Walden Bury in Hertfordshire is the childhood home of Queen Elizabeth The Queen Mother, and Bhutan's decision to feature it on a commemorative issue reflects the warm diplomatic ties cultivated between the two kingdoms — ties built substantially through Bhutan's friendship with Britain during the reign of the fourth Druk Gyalpo, Jigme Singye Wangchuck. The coin was struck as part of a broader series Bhutan issued through the 1990s commemorating British royal residences and anniversaries, largely targeting the collector market rather than domestic circulation.
