The Royal Mint has announced six new UK coins for 2013, all of which will make their way into circulation this year.
The six new coin designs have been introduced to mark historically significant events:
- a 50p coin to mark the 100th anniversary of the birth of decimal coin designer Christopher Ironside,
- two new £1 coins in honour of England and Wales in a year that celebrates the 30th anniversary of the £1 coin,
- a £2 coin for the 350th anniversary of the famous Guinea
- and two £2 coins to mark the milestone of the 150th anniversary of the London Underground.
