Well there were 2 Canadian dollar coins minted in 1973. One was made of copper nickel and celebrates 100 years of Prince Edward Island. This one is worth around $2.50 USD in uncirculated condition. The other has a Mountie on the reverse and celebrates 100 years of the Mounted Police, and is made of silver and is worth around $7.50 USD.
However much someone will give you for it.
Despite not mentioning the coin's denomination, all Canadian coins dated 1971 are still worth face value.
About 25 cents
