The United Kingdom £1 Coin
After more than 30 years in the nation’s pockets, the familiar round £1 coin was replaced with an all new, 12-sided £1 coin in 2017. Released on 28 March 2017, the new £1 features a range of overt and covert security features that, when combined, protects it from increasingly sophisticated counterfeit operations, making it the most secure coin in the world.
The final specification of the new 12-sided £1 coin and method of introduction were decided after a ten-week public consultation in 2014. The consultation considered the physical and material characteristics of the coin, as well as the parameters for the transition.
Following the coin’s introduction on 28 March 2017, there was a six-month period when the current round £1 coin and the new 12-sided £1 coin were in circulation at the same time.
Her Majesty’s Treasury and The Royal Mint worked with industry throughout the co-circulation period to introduce the new coin in a manageable way and ensure the smooth return of the old £1 coins.
The round £1 coin lost its legal tender status at midnight on 15 October 2017.
However, the round £1 coin can continue to be deposited into a customer’s account at most High Street Banks in the UK. Specific arrangements may vary from bank to bank, including deposit limits. It is recommended that customers consult with their bank direct. Round £1 coins can also be donated to a charity.

The Round £1 Coin
The United Kingdom coinage is kept under constant review. By 1980, it had become apparent, that with the general decline in purchasing power, the £1 unit of currency was more appropriate to a coin than a banknote. The note was in constant use and, on average, each note only lasted nine months. A coin can last 40 years or more and, with the growth in the vending industry, it was felt that a coin would be more useful.
After consultation with many groups, including retailers and special interest groups, the government announced on 31 July 1981 that a new £1 coin was to be issued on 21 April 1983.
To make it easy to identify, the round £1 coin was thicker than other coins, while its 'yellow' colour allowed it to stand out from the cupro-nickel 'silver' coins already in circulation. The weight of the coin was largely decided based on cost and the need to allow for higher denomination coins in due course.
The reverse designs of the round £1 coin represent the United Kingdom and its four constituent parts:- Scotland, Wales, Northern Ireland and England. The first series of designs took floral emblems as its theme, while the second series was heraldic.
The £1 coin is legal tender for any amount.
