No, and actually coins are not even made from copper at all because it is too expensive.
The were no British or Australian coins made from pure copper in 1915. Pennies, Halfpennies and Farthings were made from bronze which was about 97% copper.
Irish (Eire) "copper" decimal coins issued from 1971 to 1988 were made from bronze consisting of about 97% copper, the remainder being tin and zinc. Irish (Eire) "copper" decimal coins issued from 1988 to 2001 were made from copper plated steel.
British coins of copper appearance, the 1 and 2 Pence coins, are made from copper plated steel. British coins of silver appearance, the cupro-nickel 5, 10 and 50 Pence coins, are made from 75% copper and 25% nickel. British 20 Pence coins, are made from 84% copper and 16% nickel.
The 'copper' (1p & 2p coins) are made from 97% copper - and 3& trace elements. The 'silver' coins are made from nickel-plated sheet steel.
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.

Old coins were made from copper.
copper
Coins are typically made of a combination of metals, which can include copper, nickel, and zinc. The specific composition can vary depending on the country and denomination of the coin. Some older coins were made primarily of copper, but modern coins often consist of a blend of different metals to increase durability and reduce production costs.
Older coins were made of different metals, such as silver or copper. Coins that used to be silver are now nickel or nickel-coated copper, and coins that were copper are now copper-coated steel or zinc.
Up until recently, copper coins contained very small quantities of tin, zinc or even aluminium, and were perhaps more accurately referred to as bronze coins. Currently, due to the increasing cost of copper, there is a trend away from minting copper coins, and many, what were previously copper coins, are now being made from copper plated steel.
