3 Rupees - Jigme Dorji Ascension

Bhutan's 1966 coinage program marked the country's first modern machine-struck silver issues, produced to commemorate Jigme Dorji Wangchuck's formal ascension as the third Druk Gyalpo. The coins were struck at the Indian Government Mint in Calcutta — Bhutan having no mint facility of its own — as part of a broader modernization effort that also introduced Bhutan's first paper currency that same decade.

KM#32a is the silver variant of a type also struck in copper-nickel, distinguished by the .925 fineness and substantially heavier planchet.
