the Royal Arms is symbolic of the whole of the United Kingdom and as such, represents Wales, Scotland, England and Northern Ireland." Designer Dent stated "I am a Welshman and proud of it, but I never thought about the fact we did not have a dragon or another representation of Wales on the design because as far as I am concerned Wales is represented on the Royal Arms. This was never an issue for me." The Royal Mint's choice of an inexperienced coin designer to produce the new coinage was criticised by Virginia Ironside, daughter of Christopher Ironside who designed the previous UK coins. She stated that the new designs were "totally unworkable as actual coins", due to the loss of a numerical currency identifier, and the smaller typeface used. The German news magazine Der Spiegel claimed that the redesign signalled the UK's intention "not to join the euro any time soon". Changes after 2008 As of 2012, 5p and 10p coins have been issued in nickel-plated steel, and much of the remaining cupronickel types withdrawn, in order to retrieve more expensive metals. The new coins are 11% thicker to maintain the same weight. There are heightened nickel allergy concerns over the new coins. Studies commissioned by the Royal Mint found no increased discharge of nickel from the coins when immersed in artificial sweat. However, an independent study found that the friction from handling results in four times as much nickel exposure as from the older-style coins. Sweden already plans to desist from using nickel in coins from 2015. In 2016, the £1 coin's composition was changed from a single-metal round shape to a 12-sided bi-metal design, with a slightly larger diameter, and with multiple past designs discontinued in favor of a single, unchanging design. Production of the new coins started in 2016, with the first, dated 2016, entering circulation 28 March 2017. In February 2015, the Royal Mint announced a new design for the £2 coin featuring Britannia by Antony Dufort, with no change to its bimetallic composition. Edge inscriptions on British coins used to be commonly encountered on round £1 coins of 1983–2016, but are nowadays found only on £2 coins. The standard-issue £2 coin from 1997 to 2015 carried the edge inscription . The redesigned coin since 2015 has a new edge inscription , Latin for "I will claim the four seas", an inscription previously found on
