The £2 coin was first introduced into the United Kingdom in 1986 to commemorate the Commonwealth Games in Edinburgh. But it didn't come into circulation until 1998. Its introduction was primarily driven by the need to modernize the country's currency system. The decision to introduce a £2 coin was also influenced by the desire to create a coin that would be more durable and long-lasting compared to paper banknotes. The coin was designed to be distinctive and easily distinguishable from other coins, featuring a bi-metallic composition and a unique shape to ensure its recognition and prevent counterfeiting. Since its introduction, the £2 coin has become a popular and widely used denomination in the UK.
