In late 2011 Canadian notes switch from cotton/paper to plastic which makes braille dots easy and durable.? Each denomination of note is also a different colourCanadian coins are the same denominations as US coins and are mostly the same size.? In Canada the five cent piece was likely called a nickel because when the original silver 5 cent piece, that was smaller than a dime, was replaced by a larger coin of base metal, it was nearly pure nickel.? Canada also has a 50 cent piece, but like the US they are not circulated much.? The last time I relieved one in change was 40 years ago when crossing the international bridge at Cornwall ON. the toll was an even half dollar increment so when you got change for the toll gates they gave you 50 cent pieces.? I still have one or two of them. Paul.
