The twenty pence coin, often referred to as the 20p, is a denomination of currency in the British pound system. It is a small, seven-sided coin made of nickel-brass, featuring the image of the Royal Arms on one side and a design that varies, often showcasing British wildlife or cultural symbols, on the other. Introduced in 1982, the twenty pence coin is commonly used in everyday transactions in the United Kingdom. It is part of the decimal currency system, where 100 pence make up one pound. The coin's unique shape helps distinguish it from other denominations, making it easily recognizable.
