Watch shiny discs of metal tumble through giant machines and conveyor belts in the mint before they’re stamped and made officially into Canadian one cent pieces. How Do They Make Money? is a 1999 wordless short film by Tina Keeper for the National Film Bureau of Canada. From CBC News:
Until 1997, the penny’s composition was at least 95.5 per cent copper… From 1982 until 1996, the shape of the penny was 12-sided rather than round.
In 1997, the penny’s composition changed to 98.4 per cent zinc, with the rest copper plating. Since 2000, its composition has been 94 per cent steel.
Due to production costs and perceived usefulness, Canadian penny production was discontinued in May 2012, and the Royal Canadian Mint stopped distributing them on February 4, 2013.
