Editing Taming The Westmark (section)

===Coinage===
Most modern coinage in the Westmark is minted by Xian
*The copper “stalk” is the smallest coin of exchange, named for the rice shoot crudely stamped on one face, the other being embossed with the name and year of the current Mandarin. 
*The silver “wheel” is stamped with the Wheel of Rebirth on one side, and the image of the current Mandarin and his regnant year on the other. 
*The gold “koku” is a coin carefully marked with a basket of rice on one side and an intricate pattern on the other.  The tools used to fashion these coins leave a milled, ridged edge around its rim. Should a clipper try to shave the edges, the milling will be worn down. When it is no longer possible to tell one ridge from the next, the coin is no longer valid as currency, and must be turned in to the Xianese treasury to be re-minted. 
*1 gold koku = 10 silver wheels = 100 copper stalks
