What is englands currency made of?

England's currency, the pound sterling (£), is made of either polymer or cotton paper. The polymer banknotes were introduced in 2016 and are made from a thin, flexible plastic material. They are more durable and resistant to wear and tear than the paper banknotes, and they also have several security features that make them harder to counterfeit. The cotton paper banknotes are still in circulation, but they are being gradually phased out in favour of the polymer banknotes.
