In the meanwhile the position of copper was in no way improving. By an edict issued on December 7, 1905, the operation of the copper mints was suspended for three months, but very soon minting was resumed under the nominal control of the Board of Finance. In 1905 there were sixteen copper mints and 846 coinage presses, the capacity of which was 16 billion coins a year. The provincial Governments continued to view the issue of copper coins as the easiest means of raising revenue; hence the output was not regulated by the demand - the result being depreciation of the cash with every addition to the existing issues. An authority put the outputs for 1904, 1905, 1906, 1907 and 1908 at 1,693,700,000, 7,500,000,000, 1,709,384,000, 2,851,200,000 and 1,428,000,000 pieces respectively. There is no statistics of the total in 1909; but it is known that the mint at Mukden issued 23,609,267 pieces of 10 and 20 cash, and the Tientsin mint issued a total of 138,387,500 20- 10- 5- and 2-cash pieces. In 1910 the estimated value in silver of the total copper issue was about Tls. 100,000,000.
