It can also be known as penny social, penny sale, tricky tray or pick - a-prize according to local custom, or to avoid causing offense . </P> <P> It is unclear whether this type of auction actually originated in China; it is much more likely that the term derives from "chance auction," which is also another name for this type of auction . The term "Chinese" may have been used in this case to convey that this type of auction was mysterious, intriguing, or secretive; possibly, it may have more derogatory connotations related to stereotypes of Chinese immigrants to the United States in the late 19th century . </P>

Where did the term tricky tray come from
