The "Churchill Dollar" more correctly known as the British 1965 Crown (Five Shillings) Churchill Commemorative coin is made from a copper-nickel alloy as have all circulating British "silver" coins since 1947.
You are probably referring to the 1965 commemorative Crown (a denomination equal to 5 shillings, or a quarter of a British pound) issued in Great Britain. The coin is larger and thicker than a US silver dollar, and there is a portrait of Queen Elizabeth the Second on the front, and a portrait of Winston Churchill on the back. It is worth about a dollar in circulated condition.
