1955 To 1959
After the Battle of Chamdo in 1950-51 the renewed interference of the Chinese resulted in a situation where no more coins were struck from 1955 and 1959. However, paper notes of 100 srang were still printed. In the early 1950s the Chinese restruck dollars with the portrait of Yuan Shikai in the Chengdu mint. These were introduced into Tibet to pay Tibetan workers involved in road building and to buy the goodwill of influential Tibetans. Many Yuan Shikai dollars were smuggled to India by Tibetan traders who bought western goods in Calcutta which they sold at considerable profits to Chinese Army members in Lhasa.
