- The £1 coin depicts the whole of the Royal Shield
- The standard-issue £2 coin design remains unchanged
The 1p, 2p, 20p and 50p coins have smooth edges. The 5p, 10p, £1 and £2 coins have milled edges. The milling, in combination with the non-circular shape of the 20p and 50p, serve as the primary means of identification and differentiation between coinage for blind or visually impaired people. Historically, milling also served to discourage coin clipping.
The £1 coin and £2 coins have, inscribed into the milling, words or a decoration related to their face design. Many issues of the £1 coin carry one of the following edge inscriptions:
- DECUS ET TUTAMEN — Latin for "An ornament and a safeguard", a phrase taken from Virgil's Aeneid, and here referring to the fact that the inscription serves both as a decorative feature and as a safeguard against the clipping of the coin's edges (this is not a modern concern, but harks back to the days when circulating coins were made of precious metals). This appears on coins with English-themed, Northern Irish-themed or general UK-themed designs.
- PLEIDIOL WYF I'M GWLAD — Welsh for "True am I to my country", from the Welsh national anthem. This appears on coins with Welsh-themed designs.
- NEMO ME IMPUNE LACESSIT — Latin for "No-one provokes me with impunity", the motto of the Order of the Thistle. This appears on coins with Scottish-themed designs.
The standard-issue £2 coin carries the edge inscription STANDING ON THE SHOULDERS OF GIANTS. Other designs of the coin are issued from time to time to commemorate special events or anniversaries. These may have special edge inscriptions relevant to the theme, or the edge inscription may be replaced by a decorative motif.
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).
Outside the United Kingdom, the British Crown Dependencies of Jersey and Guernsey use the pound sterling as their currencies. However, they produce local issues of coinage in the same denominations and specifications, but with different designs. These circulate freely alongside UK coinage and English, Northern Irish and Scottish banknotes within these territories, but must be converted in order to be used in the UK. The island of Alderney also produces occasional commemorative coins. (See coins of the Jersey pound, coins of the Guernsey pound, and Alderney pound for details.). The Isle of Man is a unique case among the Crown Dependencies, issuing its own currency, the Manx pound. While the Isle of Man recognises the Pound Sterling as a secondary currency, coins of the Manx pound are not legal tender in the UK.
The pound sterling is also the official currency of the British overseas territories of South Georgia and the South Sandwich Islands, British Antarctic Territory and Tristan da Cunha. South Georgia and the South Sandwich Islands produces occasional special collectors' sets of coins. In 2008, British Antarctic Territory issued a £2 coin commemorating the centenary of Britain's claim to the region.
