How rare is a dime with fish on it?

A dime with a fish on it isn't very rare. There are 63 million of these 10 cents coins featuring an Atlantic mackerel and Queen Elizabeth II (1952-?). It commemorates the centennial of the Canadian Confederation. It contains .060 of an ounce of silver and it may currently be worth about .60 to $1 depending on amount of wear and collector demand.
