Key dates

1982

The 20p coin was introduced into circulation in June, with a view to reducing the overall weight of the coinage by decreasing the number of 10p coins in use. To make the new coin easily distinguishable, it was given the shape of an equilateral curve heptagon – the same as a 50p. With its constant rolling diameter, this shape is particularly suitable for vending machines.

2008

As part of a general re-design of the coinage, a new reverse was introduced for the 20p coin. A couple of hundred thousand pieces bearing the new reverse design were accidentally struck without a date.
