There were no coins issued in 1977 to commemorate Churchill. The 1965 cupro-nickel five shillings issued in 1965 to commemorate his death are worth from 50p to £1. In 1977 Queen Elizabeth II commemorated her silver jubilee. 25p coins were issued in cupro-nickel (now worth 30p - 50p) and those made in silver have a scrap value of around £15.
1965 was the year of Winston Churchill's death. Britain issued a commemorative Crown (Five Shillings) coin with Queen Elizabeth II on the obverse and Winston Churchill on the reverse.

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.
What you have is a copper-nickel commemorative crown (5 shillings in the pre-decimal system). Unfortunately, it is incredibly common and only worth about a dollar or two (about 50p-1 pound) if perfectly uncirculated, and not much if circulated.
The Prime Minister at the time was Winston Churchill and the Monarch was Queen Elizabeth II.
He was made a knight of the realm by Queen Elizabeth II in 1953
She didn't want to die
Queen Elizabeth II is not. Queen Elizabeth the Queen Mother was.
If it is uncirculated and in mint condition, or a cased "Proof" coin, coin collectors or maybe a coin dealer will buy it.
She wasn't, beyond the inter-relation of all of humanity. Lady Randolph Churchill was born a US citizen, second daughter of Brooklyn financier Leonard Jerome.
When did Queen Elizabeth Die?
