As traditional Chinese playing cards are derived from money, this children's card game has a long and noble ancestry. The New and Exciting Game of Change for a Shilling was produced by Geo. Wright & Co., London in the early 1930s. The game was apparently devised in order to sharpen the mental faculties. Each card bears a value in old English money ranging from ½d to 8d and the game involves players calling when cards on the table add up to one shilling. [Note: The abbreviation for the old penny, d, was derived from the Roman denarius, and the abbreviation for the shilling, s, from the Roman solidus. The shilling was also denoted by the slash symbol / , also called a solidus for this reason and used today in website addresses, which was originally an adaptation of the long s.]
The old English monetary system became obsolete in 1971 when decimal coinage was introduced.
