The Royal Mint is the body permitted to manufacture, or mint, the coins of the United Kingdom. The Royal Mint originated over 1100 years ago, producing coins for England and eventually Great Britain.
Since 2010 it has operated as Royal Mint Ltd, a company owned by HM Treasury, under an exclusive contract to supply all coinage for the UK. Royal Mint Ltd is 100% owned by HM Treasury, though the latter delegates shareholder responsibilities to the Shareholder Executive.
As well as minting coins for the UK, The Royal Mint also mints and exports coins to many other countries and produces military medals, commemorative medals, and other such items for governments, schools and businesses, being known as the world's leading exporting mint.
Responsibility for the security of the site falls to the Ministry of Defence Police, who provide an armed contingent.
In 1968 The Royal Mint began to move its operations from Tower Hill in the City of London to Llantrisant, Mid Glamorgan, Wales, and has operated on a single site in Llantrisant since 1980. At Llantrisant it holds an extensive collection of coins dating from the 16th century onwards, housed in eighty cabinets made by Elizabeth II's cabinet maker, Hugh Swann. The site occupies 38 acres (15 ha) and employs 765 people.
The annual Trial of the Pyx assays coins produced for the UK government for size, weight and chemical composition.
