“The O-Yu-Wan Area Soviet Bank was one of the first of the Communist banks to be authorized. Serving a region of the Dabie mountains at the juncture of Hupeh, Honan and Anhwei provinces, it was established in October 1930 and commenced issuing bank notes in 1931. We have already mentioned the silver dollars which were minted in 1932 for the same area. So here we have a case where the printing of paper notes actually preceded the minting of coin. To date twenty cent, fifty cent, and two types of dollar notes have been discovered. These notes picture different buildings surrounded by flagpoles. Their reverses contain stylized vignettes containing numerals of value with large square “chops” superimposed, bearing seal script.”
