Canadian money does not actually have a nickel. They have what is called a five cent piece. A 2002 Canadian 5¢ piece is only worth face value.
Its face value is 5 cents, but the melt value of a 1955-1981 Canadian nickel is $0.09 so the melt value is 4 cents more than the face value of the coin5 cents. It's not rare, and many are still in circulation.
They're both only worth face value.
Canadian nickels (1922 and later) never contained silver. A 1967 Centennial nickel is made of 99.9% nickel and is worth about 15 cents in above-average condition.
If it's been in circulation, maybe face value to 10 cents.
That's a Canadian centennial nickel from 1967. It's currently worth about 7 cents for the metal content.
