Canada never issued an 8 cent coin in 1936. I double checked my coin catalogues and found no such coin being minted in Canada or for Canada, at any time in Canada's history. You likely have a token of some sort, not Canadian currency.
Common Canadian Coins currently in circulation are: Penny (1c) Nickel (5c) Dime (10c) Quarter (25c) Dollar ($1) - Common called the "Looney" Two Dollar ($2) - Commonly called "Tooney"
There's no such coin. The first US nickels were made in 1866 and the first Canadian nickels were issued in 1922.
It's a gold bullion coin issued by South Africa, similar to the American Eagle or Canadian Maple Leaf coins. They're sold for their gold content, not for spending.
It isn't a coin, it's a medallion issued by Shell Oil. It is part of a set issued between 1967 and 1970. It was not legal currency and wasn't issued by the Canadian Mint. If you can find a collector of the medallions it's worth anywhere from .50c to a couple of dollars at most. It depends on what condition it's in.
It's a common circulation coin worth face value only.
"Loonie" is a slang term for the Canadian one-dollar coin. It gets its name from the image of a common loon, a bird native to Canada, that is featured on one side of the coin.
Unless it's uncirculated, it's a common coin worth only face value.
