Iron cash coin mints were also planned to be opened in the cities of Tianjin, Zhengding, and Daming for the production of 1 wén iron cash coins, but only Zhengding had established a mint for iron cash coins which had 10 furnaces in operation. In July of the year 1859 there were a total of 35 furnaces for the production of iron cash coins in the cities of Baoding and Zhengding and at that time around 1,000,000 strings of iron cash coins had been cast at both mints. Because the Chinese people weren't using iron cash coins it was reported that 30 furnaces in Zhengding (which presumably also includes the furnaces of the Zhili provincial branch mint) were to be closed. In November 1859, the remaining 5 iron cash coin furnaces situated in Baoding were also closed.
