The Johnson Fare Box Co. was a manufacturer of Fare Boxes that enabled the viewing as the coin was deposited and receipt of a fare from a passenger - see reference. The MMTB Footscray X1 class trams used fare boxes in 1926 and this may have been a sample coin to show how it worked. See item 7470 for an associated pamphlet that notes the use of Fare Boxes.
