"1p" refers to a one-penny coin used in the currency system of the United Kingdom. It is part of the British pound sterling and is often represented by the symbol "p." The coin is made of copper-plated steel and features the image of Queen Elizabeth II on one side, while the reverse side typically displays a design that varies depending on the year of minting. The 1p coin is the smallest denomination in the UK currency system and is commonly used for small transactions. Although its purchasing power has decreased over time due to inflation, it remains in circulation and is often used in everyday purchases, such as snacks or small items.
