Bullion
  
Not to be confused with “bouillon” cubes, which are used for cooking, bullion are bars of gold and/or silver that are certified as being at least 99.5% pure.
Jack’s mother sent him to the market to sell the family’s cow but, en route, he met a man who convinced him to trade the cow for some bullion beans. When he got home, Jack planted the beans, expecting them to grow pure bars of gold and silver. Instead, a giant beanstalk sprouted, and Jack’s mother put him in a time-out for a year before sending him off to military school to learn discipline. Neither of them ever climbed the beanstalk. Oh well.
