There would be many companies and individuals melting down old coins to recover the precious metals.
It should be noted that they do it to make money for themselves, not for the benefit of a quick buck to the owner of the coin.
If you have such a coin, you may find you will get more for it if you take it to a coin dealer, or a coin collector if you know of one.
It should also be noted that melting down or otherwise destroying "circulating coins" would be considered a crime in many countries.
Yes they do. No British decimal general circulation coin has any silver content at all. The "silver" coins of all Commonwealth countries similarly have no silver content.
Coins struck for circulation in the US today have no silver in them.
All New Zealand silver coins from 1933 to 1946 had a silver content of 50%. From 1947 onwards, all New Zealand "silver" coins were made from a copper-nickel alloy.
There have been six King Georges from 1714 to 1952. 1919 and 1920 were the two years when the British silver coinage was debased from 0.9250 to 0.5000 silver. Which year the change was made depends on the denomination of the coin. Prior to 1919/1920, all British "silver" coins had a 92.5% silver content. From 1919/1920 to 1946, all British "silver" coins had a 50% silver content. From 1947 to present, all circulating British "silver" coins had a 0% silver content.
None.
1837 was the year US silver coins changed to .900 silver & .100 copper, that caused a slight reduction of silver.

Jewelers and coin dealers buy gold and silver.
Pre-1965 silver coins are worth more for the silver than face value.
All New Zealand "silver" coins from 1933 to 1946 inclusive had a 50% silver content. All New Zealand "silver" coins from 1947 onwards, were made from a copper/nickel alloy.
Until the end of WW1, many countries minted silver coins with a high silver content, usually 90% or more. In 1919/20, there was a sharp increase in the price of silver and many countries reduced the silver content of some or all of their coins to around 50%. At the end of WW2 when many countries were repaying war loans or, had had their economies destroyed by the war, the silver content was reduced further, or eliminated altogether. By the second half of the 20th century, most "silver" coins were made from a copper/nickel alloy. These days, only non-circulating investment coins or high value coins are made from silver.
