Since 1992, copper is only used in British "silver" coins in an alloy with nickel, most commonly 75% copper and 25 % nickel giving the coins a silver appearance.
The combination of copper and nickel gives a hard wearing and durable coin that is resistant to corrosion.
Low denomination coins such as the Penny and 2 Pence coins became too expensive to be making from bronze, which has a high percentage of copper.
Steel is relatively cheap and very hard wearing, and the copper plating is for visual appeal.
The Royal Mint expects to get 40 to 50 years use from a coin.
British copper plated steel 1 and 2 Pence coins were introduced in 1992.
Pure copper has not been used to make British coins for about 150 years. From 1860, British "copper" coins were made from bronze which consisted mostly of copper varying from 95 to 97% copper. From 1992, British "copper" coins were made from copper plated steel. Ironically, copper is used to make modern "silver" coins (cupro-nickel) consisting usually of 75% copper and 25% nickel.
The lowest denominations of current UK coins will be attracted to a magnet. In the UK, copper-plated steel was used for 1 and 2 pence coins beginning in 1992, replacing their bronze predecessors. Steel, being an alloy of iron, can be attracted to a magnet. The 5 and 10 pence coins were changed to nickel-plated steel in 2011. These coins will also display magnetic properties. In 1998, some 1 and 2 pence coins were issued in bronze (not magnetic).
Queen Victoria featured on the obverse of all British coins from 1838 to 1901 inclusive. Many countries of the then British Empire, would have used the same British coins, or coins featuring Queen Victoria on the coins of their own currencies.

The silver used to make predecimal British coins could have been mined anywhere in the then British Empire. A lot of silver was also acquired from raids on Spanish ships.
1p & 2p coins are made of copper-plated steel. 5p 20p & 50p coins are made of copper-nickel. £1 coins are made of brass. £2 are brass on the outer ring and nickel on the inner portion The coin was initially minted from bronze, but since 1992 it has been minted in copper-plated steel except for a few months in 1998 when bronze was used again. As copper-plated steel is less dense than bronze, post-1992 coins have been slightly thicker. The coin weighs 7.12 grams and has a diameter of 25.9 millimetres. The 2p coin is currently 93% mild-steel and 7% copper.

British 20 Pence coins are legal tender in amounts up to £10 GBP.
Prior to 1933, New Zealand used mainly British coins and a some Australian coins.
