The penny is a unit of currency in the British decimal system, which was introduced in 1971. It is worth one-hundredth of a British pound, making it equivalent to one pence. The coin features various designs, but the most well-known version depicts the head of Queen Elizabeth II on one side and a design reflecting British culture or heritage on the reverse side. The penny coin is made primarily from copper-plated steel as of recent minting practices.
