Key dates

1971

1p coins were issued into circulation on 15 February, the day the United Kingdom adopted a decimal system of currency.

1982

The reverse inscription was changed from NEW PENNY to ONE PENNY.

1992

With metal prices rising on world markets, the composition of 1p coins was changed from bronze to copper-plated steel. As a result of their steel core, copper-plated steel 1p coins are magnetic.

2008

As part of a general re-design of the coinage, a new reverse was introduced for the 1p coin.
