coins bearing the image of Britannia. Other commemorative £2 coins have their own unique edge inscriptions or designs. Obsolete denominations The following decimal coins have been withdrawn from circulation and have ceased to be legal tender. * The specifications and dates of 5p, 10p, and 50p coins refer to the larger sizes issued since 1968. † The specification refers to the round coin issued from 1983–2016. Although obsolete, this coin is still redeemable at banks and the British railway systems, and is still legal tender on the Isle of Man. Commemorative issues Circulating commemorative designs Circulating fifty pence and two pound coins have been issued with various commemorative reverse designs, typically to mark the anniversaries of historical events or the births of notable people. Three commemorative designs were issued of the large version of the 50p: in 1973 (the EEC), 1992–3 (EC presidency) and 1994 (D-Day anniversary). Commemorative designs of the smaller 50p coin have been issued (alongside the Britannia standard issue) in 1998 (two designs), 2000, and from 2003 to 2007 yearly (two designs in 2006). For a complete list, see Fifty pence (British decimal coin). Prior to 1997, the two pound coin was minted in commemorative issues only – in 1986, 1989, 1994, 1995 and 1996. Commemorative £2 coins have been regularly issued since 1999, alongside the standard-issue bi-metallic coins which were introduced in 1997. One or two designs have been minted each year, with the exception of none in 2000, and four regional 2002 issues marking the 2002 Commonwealth Games in Manchester. As well as a distinct reverse design, these coins have an edge inscription relevant to the subject. The anniversary themes are continued until at least 2009, with two designs announced. For a complete list, see Two pounds (British decimal coin). From 2018–2019 a series of 10p coins with 26 different designs was put in circulation "celebrating Great Britain with The Royal Mint’s Quintessentially British A to Z series of coins".

They are usually legal tender, but worth only their face value to pay debts. For example, in 2023 a 50 pence piece was announced, the first coin depicting King Charles III, and celebrating the fictional wizard Harry Potter. The standard version sells for £11 and a colour version for £20. Other versions range up to
