1 Tangka 'Kong-par Tangka', type 1, single circle

The Kong-par Tangka takes its name from Kongpo, the region where this coinage was produced under direct Qing supervision following the Gurkha invasions of Tibet in 1788 and 1791. The second Gurkha incursion prompted the Qianlong Emperor to dispatch a 17,000-strong expeditionary force under General Fuk'anggan, which expelled the Gurkhas and then imposed sweeping reforms on Tibetan administration — including its coinage. This type, struck in 1792–93, predates those reforms taking full effect and represents the transitional moment before Beijing asserted tighter monetary control over Lhasa.
