The 'copper' coins are in fact copper-clad steel nowadays, although older ones are bronze.
From 2011 5p and 10p coins are in nickel-clad steel, although earlier ones are cupronickel.
20p and 50p coins are minted in two slightly different copper-nickel alloys.
Pound coins are in nickel-brass, while two pound coins are in nickel-brass with a cupronickel centre.

The British 20 Pence coin was first issued on the 9th of June, 1982. The 20p denomination was first minted in 1982. It was introduced to help with change-making, because people were finding themselves awash in 10p coins. The situation was made worse because at that time the 10p coin was the same huge size as the old florin that it replaced after decimalisation. The 20p coin is also notable because it was the first decimal coin to have its denomination expressed simply in pence rather than "new pence".

As a general "rule of thumb", most, if not all predecimal British coins would have some value beyond face value, if only for the metal they are made from. As another general "rule of thumb", most British decimal coins will have only face value other than for "uncirculated" or "Proof" coins and the very occasional error coin such as the undated 20 Pence coin and the 1983 2 New Pence coin.
