In 1968, in response to the challenge of decimalisation, an advanced facility was established in Llantrisant, South Wales, to replace our existing production site at Tower Hill. Opened by Queen Elizabeth II in 1968, the transition to Wales was finalised in 1975.  The last coin to be struck at Tower Hill, a gold Sovereign, was minted in November of that year, and the following year, production of the 1976 Sovereign began, making it the first to be produced in Wales.
