This is a platform ticket machine located in the museum at Kidderminster station. The 1 D indicates a platform ticket costs 1 penny. Old English currency used to be in Pounds, Shillings, and Pence, as indicated by £, s, and d. There were twenty (20) shillings to the pound. The shilling was subdivided into twelve (12) pennies. The penny was further sub-divided into two halfpennies or four farthings (quarter pennies). This pre-decimalisation British system of coinage was introduced by King Henry II. It was based on the troy system of weighing precious metals. The penny was literally one pennyweight of silver. A pound sterling thus weighed 240 pennyweights, or a pound of sterling silver. There were therefore 240 pennies to the pound.
