The price of silver rose significantly during the 20th Century and most, if not all countries, ceased using silver in their general circulation coins at some time during the 20th Century.
Britain ceased the use of silver in 1946 when they needed the silver to repay war loans to the USA. Britain had already reduced the silver content of coins to 50% in 1919.

How do you know when your coins are silver?
You can determine if your coins are made of silver by checking the coin's composition, minting year, and any mint marks. Silver coins typically have a higher silver content than other metals like copper or nickel, and some may even be marked as "silver" on the coin itself. Using a coin scale or magnet can also help determine if your coin is silver.
What year did the US mint start adding copper to coins?

What happens when a silver spoon is kept immersed in aqueous copper sulphate solution?
When a silver spoon is immersed in aqueous copper sulphate solution, a displacement reaction occurs. The silver spoon will react with the copper sulphate, displacing the copper ions and forming silver sulphate solution. Over time, the silver spoon will start to turn slightly reddish as a thin layer of copper is deposited on its surface.
Why did romans coins decrease in value during the ad 200s?
Because the coins were made of debased (less pure) silver. The Roman Denarius was the basis of the currency system.

The first US dimes and quarters were minted in 1796. They continued to be struck from silver until 1964 when the rise in silver prices forced the Mint to change to the current copper-nickel clad composition. Silver half-dollars and dollars were first minted in 1794. Halves were changed to a 40% silver composition from 1965 to 1970, and were finally changed to copper-nickel in 1971. Silver dollar production ended in 1935. The denomination was resumed in copper-nickel from 1971 to 1981 and again in 1999; since 2000 $1 coins have been minted in manganese brass.
